WHY INERTIA?
All rights reserved
Aristotle postulated the connection between force and motion in 350 B.C. Galileo furthered
these views some 2000 years later. Sir Isaac Newton formalized the concept in 1687. The
first of the three laws of motion is the Law of Inertia. The law of inertia states that a body,
or mass in motion will continue in that motion until an outside force acts upon it to cause a
reaction. Likewise, and object at rest will remain at rest without an external influential force.
Perspective is the key to inertia. Which force is being acted upon, and which is causing the
reaction, the inertia of both bodies is changed by their contact with one another. Inertia
Engineering and Machine Works strives to be the force of change while reacting to industry
needs. We trust that our products will change and improve technology that will make
positive impacts on the electrical power distribution industry.

technology to break current loads up to 900 amps at 27 kV. It is
used for load-break, loop break, line charging and cable charging
switching operations. The AmpRupter was tested to IEEE 12471998 IEEE Standard for Interrupting Switches for Alternating
Current Rated Above 1000 Volts. The mechanical life of the
AmpRupter is 2,500 operations. The electrical life of the AmpRupter
is dependant on the amount of load interrupted.
AmpRupter load interruption occurs as the switch blade leaves the contact clip; making contact with the catch
arm. At this point, current is shunted through the actuator arm, through the contacts to the load side. As the
blade continues towards its open position, the internal spring powered mechanism trips; breaking the internal
contacts. This action evolves a pressurized non-conductive gas that extinguishes the arc. This process occurs
within one half cycle (first zero crossing), and will not “chop” the current upon circuit interruption. The speed of
the AmpRupter mechanism is not dependent on the switch operating speed, insuring that the load breaking
capabilities are consistent regardless of switch opening speed. The AmpRupter automatically resets for the
next operation. The AmpRupter is not in the current path during the switch closing operation, and has no fault
closing capabilities. The AmpRupter is in the current path during the switch opening operation only.
AmpVac™
LineBOSS™ Selection Guide suffix “V”
V2 (2-gap vacuum Interrupter)
V3 (3-gap vacuum Interrupter)
LineBOSS™ 46 kV - 69 kV Selection Guide suffix “V2”& “V3”
The AmpVac is an enclosed vacuum bottle interrupter where no
gases are vented to the atmosphere. The AmpVac interrupter
has much higher interruption capabilities than other load break
devices. Single contact AmpVac interrupters break loads up to
1500 amps at 35 kV. Single vacuum bottle interrupters may be
used at reduced voltages for parallel or loop switching applications
as long as the peak recovery voltage does not exceed 38 kV. The
mechanical and electrical life of the AmpVac is 5000 operations at
full load. The AmpRupter was tested to IEEE 1247-1998 .
The V2 and V3 vacuum Interrupters are a two-gap and three-gap
load-breaking devices, respectively that utilize vacuum bottle
technology. V2 vacuum interrupters with two vacuum bottles in
series can break loads up to 2000 Amps at 48 kV. V3 vacuum
interrupters with three vacuum bottles in series can break loads
up to 2000 Amps at 69 kV. Vacuum bottle interrupters are not in
the current path during the switch closing operation, and have no
fault closing capabilities. The mechanical and electrical life of the
V3, 3-Gap vacuum interrupter is 5000 operations at full load.

ArcChute (Delrin “Clapper”)
Quick-break Whip
Return to Section 2 Contents
LineBOSS™ Selection Guide suffix “H”
The ArcChute Interrupter is a minimal load-breaking device that
utilizes air break technology. The arc is quenched as the two Delrin
arc chute plates close and the arc whip breaks away establishing
the required metal-to-metal open gap. Arc Chute interrupters are
widely used for line charging and magnetizing current interrupting.
Full loadbreak and parallel breaking currents up to 150 amps at
21kV or 20 amps at 34.5kV are common applications. Arc Chute
interrupters are only in the current path during the opening process
and have an average life of 150 operations.
LineBOSS™ Selection Guide suffix “Q”
The Quick Break Whip is similar to an Arc Horn, but unlike Arc
Horns, the Quick Break Whip has a small interrupting rating
between 10 and 20 amps. Quick Break Whips can clear arcs
from residual energy stored in capacitor banks, transformers or
conductors. Quick break whips are only in the current path
during switch opening operations. Quick break whips have an
average life of 150 open operations.
LineBOSS™ Selection Guide suffix “A”
The Arc Horn is not an interrupter and has no ratings. It is used as
an arc deflecting mechanism to save the life of switch blades and
contact clips. The ArcHorn, also known as “sacrificial arcing horn”,
is the first point of contact during switch closing operations. The
initial making current during a closing operation creates small arcs;
pitting the arc horns. This “sacrificial” mechanism prevents
degradation of the main contacts. The Arc Horn is used to redirect
the arc resulting from residual or stored charge left in a line after a
down-line circuit is opened. Arc Horns will not prevent damage
from the inadvertent opening of a loaded switch.

Some rotating insulator spindles and bearings are supported solely
on the 3/16” thick phase base surface. The spindle and its bearing
should be supported at both the phase base surface and the end of
the spindle opposite the blade. A 1/4” thick base supporting the
rotating stack at two points assures a robust construction that maintains the blade to contact alignment throughout the life of the switch.
Some rotating insulator spindles are made of zinc chromate plated
steel which can rust. Others use cast aluminum which is inexpensive, but has poor wear characteristics and does not have the
strength of steel. Switches can come out of contact adjustment if a
spindle bearing fails. The added benefit of stainless steel and brass
ensures a long reliable switch life.
Bearings in the bellcrank reduce the force required to operate the
switch and eliminate corrosion due to plated metal-to-metal wear.
These insulators have superior mechanical characteristics over 2¼”
BC insulators. Silicone insulators have additional BIL, leakage and
weatherabilty ratings over either porcelain or epoxy insulators.

Busbar grade copper contact components are structurally superior
with greater conductivity than cast contact material. Cast aluminum and copper bronze contact castings are 34-36% conductive
and often contain unseen surface irregularities and voids that create ‘hot spots’. Busbar grade C110 copper is 99% conductive and
is many times smoother to provide better terminal connection surfaces and is not subject to unseen porosity. With this contact system, the LineBOSS has achieved the highest momentary and fault
close ratings in the industry. Momentary: to 70 kA for 10 cycles and
44 kA for 3 seconds. Fault close: 30 kA (2X)
Often, switch manufacturers use cast clamps to connect the interphase rod to the rotating stacks. This clamping method has one
fixed side and only one open side to pinch the interphase rod. The
interphase rod clamp is the device that assures uniform operation
of the three switch phases. Any slippage results in an improperly
adjusted switch, with not all phases fully closed into the contacts.
The LineBOSS uses formed two-piece clamps to compress the interphase rod surface with significantly more distributed pressure.
This helps to maintain uniform operation of all three phases throughout the life of the switch.

The Inertia hookstick operated switch eliminates the need for a control rod, so
there is no need for any field adjustment of the switch. Compression of the
blades into the clips and interrupter timing are factory set. Without lower controls; pole clutter is reduced.
Hookstick operating mechanisms are available on Horizontal, Underarm horizontal, Riser, Vertical (phase over phase) and Delta (triangular) configurations.
The Inertia Hookstick safety features include:
1.) Hookstick mechanism is located below the xarm, away from hot parts.
2.) No springs that could be effected by ice.
3.) The switch bellcrank has built-in toggle-over in both the open and closed
positions, which in conjunction to the lock-out bar feature, prevents inadverte
n
t
operation of the switch from either position by perching wildlife.
4.) For night and inclement weather operation, the “hook” positions are highlighted
with a high visibility, yellow reflective surface.
The Inertia Hookstick bellcrank and rotating stacks have stainless steel-to-brass
shaft bearings. Consider the savings in restrictive losses when the control
rods, guides and handle are no longer a factor! This makes the Inertia Hookstick
operated switch the easiest switch to operate. High leverage cam action

46 kV & 69 kV Sidebreak Type,
Gang Operated Air-break Switch
69 kV Twin Circuit construction with outboard reciprocating control shown here.
INERTIA Engineering and Machine Works, Inc.
adapted the industry leading design features of its distribution class G.O.A.B. switches, to produce an extremely high quality and cost effective, unitized sidebreak style transmission switch.
The ease of installation that unitized distribution class
switches provide is now available for transmission
class switches. The phase units are shipped as completely factory assembled and adjusted units. The
actual configuration is delivered fully unitized or modularized for fast, simple and easy field installation.
The LineBOSS 46- 69 kV sidebreak switches are the
lowest “cost to own” switches available today. Fully
unitized or modular switches are hung on the pole in
hours, not days. These switches also provide lower
operating costs. Unbalanced conductor load or seasonal temperature changes can create line sag leading to contact misalignment on other style switches.
This maintenance headache is eliminated by the
LineBOSS sidebreak switch. Custom phase bases are
available for installation on a wide variety of structures.

46 kV & 69 kV 600-1200 Amp
Sidebreak Style Switch
Features and Benefits
Unitized transmission switches install with the speed and ease of distribution
switches and provide years of maintenance-free operation.
Specify these features for the lowest installed, lowest operating cost switch.
FEA
TURES
FEATURES
BENEFITS
Unitized/Modular
Switches
The LineBOSS™ 46 kV and 69 kV switches come from the factory with
each phase unit completely unitized and adjusted. When the switch
configuration calls for partial assembly, the LBS switch is broken down
into easily assembled modules. The locations of the modules are
fixed, requiring very little, if any, adjustment.
All rights reserved
Benefit: Greatly reduced installed cost with minimal field assembly and
adjustment of the switch.
Interlocking phase
base design with
through-hole
mounting bolts.
The LBS 46 kV and 69 kV phase units have an interlocking design that
securely clamps and locates each phase unit on the crossarm. Secure
phase bases result in minimal movement over the life of the switch.
Adjustments to the switch are virtually eliminated. The through-bolt
fastening assures that user specified phase spacing is met without
additional field measurements or adjustments.
Benefit:
Bearings in the bellcrank mechanism reduce the force required to
operate the switch and eliminate corrosion caused by plated metal-tometal abrasion and wear.

Reduced installed cost due to minimal assembly
Reduced maintenance cost through secure clamping
Benefit: The ease of operation reduces risk of injury to personnel
operating the switch and also translates into greater switch life.
Inertia uses busbar grade copper contact components as they are
structurally and electrically superior to cast contact materials. Cast
aluminum and copper bronze contact castings are 34-36% conductive and often contain unseen surface irregularities and voids that
create ‘hot spots’. Busbar grade C110 copper is 99% conductive and
is many times smoother to provide better connection surfaces and is
not subject to porosity.

components.
Benefit: Reduced operating cost due to a cooler running switch.
Longer service life with reduced energy loss.
ANSI TR2xx series,
3” (46kV) & 5”(69kV)
bolt circle station
post insulators are
provided in silicone
or porcelain.
Sealed stainless
steel ball bearings
on rotating stacks
The LBS switches are offered with silicone or porcelain, three inch (3”)
and five inch (5”) bolt circle station post insulators. Silicone insulators
are standard, with porcelain available as a lower cost alternate.
Benefit: Silicone insulated switches are lighter and easier to install with
minimal chance of damage when uncrating and erecting.
Porcelain insulators provide a lower cost option.
The rotating insulators pivot on double sealed stainless steel ball bearings at both the top and bottom of the phase base providing smooth
maintenance-free operation of the switch throughout its life.
Benefit: Total operating cost of the switch is reduced as less site visits
are required for maintenance.

LineBOSS NBS
NBS, 5 kV -
38 kV Non-Interrupting
Regulator/Bypass, Overhead Switch
The LineBOSS™ NBS, Nielsen Bypass Switch, was
originally designed in 1972 by Carl Nielsen, P.E. to
allow non-interrupting bypassing and energizing (cutin or cut-out) fixed booster transformers. The NBS
switch now provides continuous power to load-side
customers when energizing or de-energizing one, two,
or three phase fixed booster, auto-booster and
regulator transformers as required by voltage
conditions or for routine maintenance or replacement.
The conventional combination bypass-disconnect
switch used for de-energizing multi-step regulators; first
requires the regulator be placed in the neutral position.
As the switch opens, a shorting bar is inserted across
the main line leads and the regulator series winding.
If the regulator tap changing mechanism or the position
indicator has malfunctioned and the regulator is not in
the neutral position, attempting a by-pass operation
can result in excessively high circulating current in the
series winding which can damage or destroy the series
tap changer mechanism, the switchgear, bus work and
endanger personnel.
The NBS bypass switch eliminates this safety hazard
by controlling the series winding circulating current by
use of a current limiting resistor, while providing
uninterrupted service to load side customers. The
transfer series resistor assembly permits bypassing
multi-step regulators in the buck or boost position (refer
to application calculations).
TYPICAL APPLICATION:

re-wiring the buswork. The NBS-2D is not required
on multi-step regulators.
STANDARD FEATURES
Cut in a 762 kVA (7620 V, 100 A), single-phase regulator to
boost the voltage. The regulator indicates that it is in
neutral, but it is actually at step one. The circulating
current could be as high as 31 kA during the switching
operation using a standard bypass switch. The NBS
switch, with its current limiting series resistor assembly,
limits the circulating current to less than 24 A without
interruption of service.
Voltage Class: 5 kV, 15.5 kV, 25.8 kV & 38 kV
Continuous Current Class: 600 A Transfer & Continuous
THE TWIN FEED NBS:
STANDARD CONFIGURATIONS
The NBS-2D is designed for use on fixed boosters and
auto-boosters that are on circuits that have preferred
and alternate source directions. The NBS-2D allows
the booster or auto-booster to boost in the direction of
the load when the alternate source is being utilized.
The NBS-2D provides a switching method for re-routing
the source feed to the booster transformer without

Notice that the blade is in contact

winding. These resistors are lab and
field proven to withstand 600 Amps
during the transfer operation.

LineBOSS™ NBS Switch Application Guidelines
Using a standard regulator bypass disconnect switch,
the voltage differential across the series winding in the
regulator is shorted out during the switching sequence.
This produces an extremely high current when in the
lower tap positions (not in neutral). The INERTIA NBS
eliminates this high circulating current by placing
resistance in series with the regulator series winding.
The maximum boost or buck voltage differential is
limited to 1200 volts (600 A rating x 2 ohms).
Example: Line voltage is 13,800 volts, 10% max. boost
or buck with 16 positions boost or 16 positions buck.
13,800 V x 0.10
16 tap positions = 86.25 voltage change per tap position
The maximum switching position for a given regulator
can be determined by the calculations shown:
Conclusion: The NBS will safely switch this 13,800 V
regulator at tap position 13. At step one where the
circulating could be as high as 43,125 A based on
0.002 ohms series winding impedance, the current is
mitigated to 43.1 amps while switching.
1. Determine the voltage change per step of the
regulator or booster transformer:
Printed 09/05
Voltage change/step =
(Line voltage) x (Max. boost or buck %)
Number of tap positions
2. Determine maximum boost or buck tap position:
1200 volts
Maximum tap position =
Voltage change per tap
3. Determine maximum current at tap position 1:

= 43.1 A max. circulating current

NOTE: Always attempt to return the regulator to
neutral before switching. This device is not intended
to change the safety or standard operating practice
of switching regulators.
The NBS switch allows an added margin of safety
when switching regulators. When neutral position can
not be definitely confirmed, the NBS will allow safe
switching in the “off-neutral” position as long as the
differential voltage across the transformer series
winding does not exceed 1200 V.
INERTIA’s NBS noninterrupting bypass switch, protects
personnel and equipment, and eliminates the downtime
and other costs associated with taking an outage to
switch regulators, fixed or auto-booster transformers.
It provides additional personnel and equipment safety
in line distribution and substation applications.

MSO
Motorized
Switch
Operator
The Inertia MSO, motorized switch
operator meets or exceeds ANSI certification standards for substation,
transmission and distribution Supervisory Control And Data Acquisition
(SCADA). It works as a stand alone,
locally controlled device, or it can be
fit with a wide variety of SCADA communication equipment including your
choice of RTU, modem, radio, antenna, cabling, and analog insulators
with current, voltage and fault sensing capabilities.
Two MSO models available:
• MSOR- reciprocating output for a
vertical moving control rod, and
• MSOT- torsional output, selectable
for clockwise and counterclockwise
switch opening.
The Inertia MSO is built with interchangeable communication control
modules allowing upgrade on the
shop bench instead of in the field. A
basic pushbutton operating device can
be upgraded with a variety of SCADA
systems in the future. A new or modified module, with your choice of remote control features, can be easily
bench tested on an existing MSO series and quickly apply the upgrade in
the field.
The Inertia MSO gives the flexibility
needed for your changing remote
switching requirements. Inertia’s interchangeable modules allow for easy
upgrades on the shop bench; not up
on the pole.
Physical Characteristics
The Inertia MSO is light enough to be
installed with any lifting equipment
capable of lifting up to 225 lbs. The
nominal cabinet measurements are
15 1⁄2” W x 191⁄2” H x 23”D. Manual
switch operation is provided on the
back of the reciprocating models and
the bottom of the torsional models.
Back
KEY FEATURES
• Perpetual Position Alignment
The patented clutch assembly in the
Inertia MSO provides factory adjusted output travel that never
needs resetting in the field. Once
the MSO has been installed and the
switch rod adjusted, the operator
never requires realignment, even if
the operator is partially operated in
the manual mode.
• Modular Construction
The slide-in control modules are upgradable and easily interchangeable
in the field. If the RTU or radio need
replacement, the bench work is
done in the shop and the control
module exchanged in the field by the
troubleman.
• Unitized Construction
The drive mechanism is isolated
from the main cabinet, providing isolation of electronic components.
• Operating Speed
The reciprocating and 90° torsional
units operate in 0.5 to 0.6 seconds.
Clockwise or counterclockwise rotations up to 260 degrees in 1.7 to
2.0 seconds can be set at any start
or stop position.

Behind The Panel . . . . . . . . . . . . Modularity
The slide-in battery and control modules provide easy access for upgrades. Battery-pack changeouts are made
quickly and easily by separating the power plug and removing it. The INERTIA control module is custom tailored for
the customers requirements. No field wiring of the operator
is required. The control modules are interchangeable, so if
an upgrade is desired, a backup unit can be programmed
and tested in the shop and sent out to the site for replacement. The replaced module can then be returned to the
shop for bench testing. There is no need to troubleshoot
the module on the pole. Since the modules are interchangeable, the operator never becomes obsolete. As your requirements change, an upgraded module with different capabilities can be inserted with the same ease without the
need to take a clearance.

Control Modules
MSO control modules are designed with “open
architecture” and are adaptable to customer
selected specifications for power input, SCADA
status and control, and communication and fault
sensing devices.
Substation applications:
The control module can be a “hard-wired” unit
without RTU or communicatiions device for substation applications.
Control module input, control and status point information:
• External power requirement: 250 watts minimum
• Supply voltage input: 120/240 VAC or 24-125 VDC
• Control and drive power: 24 VDC
• Auxiliary power: 12 VDC, 4.5 A
• Control points* (24 VDC Form-A “wetted relays)
• Status points** (24 VDC Form-A “wetted relays)
* Form-A “dry “ contact relays are available.
** Status points can be grouped for “Condition Alarm” as requested.
Field applications:
Back
The control module can be supplied with factory
mounted and wired RTU, communication device
or both. When customer supplied, the factory will
predrill the control module frame to accept the
form factor of the device(s) to be customer installed. The RTU and/or communication device(s)
can also be installed external to the MSO in factory supplied weatherproof boxes or it can be supplied with an umbilical cord (instrumentation/control cable) with customer specified connectors.
The Inertia MSO’s mechanical and electro-mechanical drive
components are designed to last for decades. It is not likely
that any technological or material advances will improve this
drive system. Battery, RTU and communications technologies are very likely to change in the future. The removable
battery pack and control module systems allow easy upgrades without field wiring. Future upgrades of the RTU or
communications device will be done in the shop on replacement modules. Pretested, pre-programmed modules can
then be hot-swapped in the field without taking a clearance.

MSOR
Motorized Switch Operator,
Reciprocating
The MSOR reciprocating switch operator is the single
answer to your changing remote switching requirements.
All rights reserved
The INERTIA MSOR Series reciprocating motorized switch operator can
operate virtually any moving blade
transmission or distribution switch
with reciprocating (up/down) control.
It is the safest and most reliable of
all of the MSO operator designs. This
is true because reciprocating
switches experience much less relaxation of the control rods under
compression than do torsionally operated switches.
The MSOR has interchangeable communication/control modules that will
allow upgrades and repairs to be
made on the shop bench instead of
in the field. It can operate any ninety
degree opening sidebreak or line tension switch. The control module can
be supplied with either or both the
RTU and communication device of
your choice. If radios or other communication devices are to be recycled
or customer installed, the control
module can be predrilled at the factory to accept all devices commonly
used in your system.
Operator shown in
the open position,
engaged and
operational, with the
collar padlocked
Installing and setting up the operator
is simple. Install the switch as you
would a manual handle. The MSO
weighs approximately 225 lbs. so it
can be easily set in place using a
bucket truck. Two through-bolts are
all that is required to secure the MSO
to the pole. Operate the switch to
the closed position, install the adjustable coupling, and set the handle to
provide moderate control rod compression while allowing toggle-over.
The automated switch is now ready
for remote operation.

Stainless steel shear-nuts make repeatable and reliable electrical
connections to electrical apparatus. Zinc, die cast shear nuts can
be used for lower torque requirements. Installing rod guides, steps
and other hardware to fiberglass poles or crossarms can damage
the fiberglass pole or crossarm when excessive torque is applied.
Shear nuts mitigate this problem.

The above sizes are used for field connections to electrical equipment where specific
torque values are required to compress Belleville washers and ensure a good electrical
connection without the need for torque wrenches and the associated calibration of that tool.
Other sizes, materials and torque-limits are available. Consult the factory for your specific
needs.
