Introduction
2 Introduction
The U-Series remotely controlled and monitored
automatic circuit recloser (ACR) consists of a
U-Series automatic circuit recloser (ACR)
combined with an Advanced Controller (ADVC).
The U-Series ACR
„
„
„
„
„
„
„
„
„
consists of ganged vacuum interrupters
insulated with cyclo-aliphatic epoxy resin
mouldings,
operated by a single magnetic actuator for
both tripping and closing.
The mechanism is enclosed in a 316 grade
stainless steel tank and lid, onto which is
bolted to the cyclo-aliphatic epoxy resin
casting.
Surge arresters can be directly fitted to the
ACR (depending on mounting method) and
should be fitted at installation.
Voltages are measured on each of the I Side Bushings and can be measured on the
X - side Bushings if external VTs are fitted.
Current is measured on each phase.
The ACR itself retains information such as
serial number, switchgear type, operations
and contact wear, independently of the
ADVC.
The ACR can be tripped and locked out
mechanically from the ground by a hookstick
and then be locked out electronically by
opening the isolating switches located on the
ADVC.
A clearly visible, external pointer shows
whether the ACR is tripped or closed.
„
The ACR is connected to the Advanced
Controller (ADVC) via a control cable
through the base of the ADVC.
„ The ACR can be connected into a bare
conductor system.
The ADVC reads and displays the information
which is stored in the ACR and provides
protection and communication properties for the
ACR.
The ADVC
„
consists of:
† an operator control panel mounted in the
door,
† an electronic switchgear controller that
monitors the ACR, and provides
communication and protection functions,
† a power supply which also supplies power
for customer equipment,
† an accessories and customer equipment
compartment.
„ is powered by an auxiliary voltage supply of
110, 220, or 240 volts AC.
„ is connected to the ACR via a detachable
control cable.
The customer compartment provides ample
room for equipment. Standard communications
cables can be used for connection to the
communications ports on the ADVC and power
is readily accessible from the programmable
power terminal block. (Please refer to
“Communications and Accessories Installation”
on page 4-1.)

Testing &
Configuring
The tests can be carried out on site or in the
workshop as preferred.
Unpack the crate as above and put the HV
cables, boots and the control cable in a clean
safe place where they will not be damaged or
soiled. Make a temporary earth connection
between the ADVC and the ACR. 1mm² copper
wire is adequate for the purpose.

Raise the ACR using a crane or forklift in order
to safely gain access to the bottom of the ACR.
Unbolt the cover plate over the switch cable
entry module (SCEM) on the bottom of the ACR
and connect the ACR end of the control cable to
the SCEM.
Lower the ACR on to props so that the control
cable is not damaged by being caught between
the base of the ACR and the floor.
Then connect the ADVC end of the cable to the
socket at the lower right-hand corner of the
CAPE located inside the ADVC cubicle. (See
Site Procedure, Step 14. on page 3-3.)
The LV auxiliary supply (if applicable) should be
connected as shown in Figure 5 (page 3-5).
‘Turn on the battery and auxiliary supply circuit
breakers at the bottom of the control cubicle and
carry out the following tests:
1. Manual trip and close of the ACR.
Transport to

Site
Installation
If you are replacing a pole-top control
cubicle (PTCC) with an ADVC, the
following should be considered:
„
„
„
„
„
The ADVC mounting points will be different1.
The connection to the auxiliary supply enters
the cubicle at a different point.
The earth stud is in a different position.
Accessory cables may need extending.
Unlike the PTCC which required an
auxiliary power supply rating of 50VA, the
ADVC requires 100VA.
„
If the auxiliary supply is provided by an
external VT connected through the ACR,
there are limitations to the supply ratings of
equipment that customers may fit. In ADVC,
General Specifications See “Radio/Modem
Power Supply Continuous Current” on
page 11-4.
„ Unlike the PTCC, the ADVC has locking
hinges on the door which prevent the door
from swinging or blowing shut. When you
open the door to 180°, it locks into that
position. To close the door, disengage the
hinge locks by raising the door slightly
before rotating it.
Tools Required
„
Torque wrench and metric socket set,
normal engineers tools.
„ Tools to prepare pole as required.
„

Site Procedure
20mm sealing cable entry glands to suit
auxiliary supply mains cables, 16mm sealing
cable entry glands to suit antenna or
communications cable as required.
To erect and test the ACR and ADVC, carry out
the following steps. Mounting details are given in
Figure 6 (page 3-6):
1. Transport to site and carry out testing prior to
erection as required.
2. Connect cable tails and surge arresters
before raising the ACR. See "Surge Arrester
Mounting and Terminating" - page 3-4 .
3. Ensure that the pole is of sufficient strength
to support the ACR. A structural engineer
may be needed to calculate the stresses
involved.
4. Securely mount the ACR mounting bracket
on the power pole.
5. Lift the ACR into position and lower it onto
the mounting bracket so that it sits on the
mounting bracket. See Figure 6 (page 3-6)
and Figure 8 (page 3-8).
6. Bolt the ACR to the mounting bracket with
the four 12mm nuts and bolts provided.
Tighten to 50 Nm.
7. Complete the high voltage connections.
8. Unbolt the SCEM compartment cover plate
from the bottom of the ACR. Connect the
control cable to plug P1 1 on the SCEM
located inside the ACR. Then bolt up the
„
Antenna, antenna feeder cable, and surge
arrester as required if a radio is fitted (unless
supplied by the manufacturer).
When mounting the ADVC to a
wooden pole, use a spirit level to
ensure correct alignment, and
minimise torque on the mounting
brackets.
12. Attach the control cable to the power pole
maintaining maximum available separation
from the main earth bond (at 200mm for
wood and concrete poles and 150mm for
steel poles). Ensure that there is enough
cable available at each end to permit
connection to the equipment.
13. Run the earth connections as described in
“Earthing” on page 3-4.
It is vital that the earthing scheme
is carried out as described.
14. Push the control cable from the ACR through
the base of the ADVC 1

See Figure 4 (page 3-1) for the correct way
to connect/disconnect the control cable.
9. Run the control cable from the ACR down to
the ADVC.
10. If the ADVC is to be bolted to the pole, drill
the top hole and fit the bolt. If it is to be
strapped, feed the straps through the slots
on the upper and lower mounting brackets.
11. Lift the ADVC into position and bolt or strap it
to the power pole.
Note that the
ADVC mounts
have key holes as
shown here, so
that you can lift
the ADVC on to
the mounting bolt
and slide it into position.
15. For LV mains supply run auxiliary wiring as
shown in Figure 10 (page 3-10). Make the
connection inside the ADVC as shown in
Figure 5 (page 3-5).
16. For LV supply from a dedicated transformer
supplied by the utility, connect as shown in
Figure 11 (page 3-11).
17. For Integrated supply from an external
transformer, connect as shown in Figure 11
(page 3-11). (See also “Auxiliary Power from
Integrated Transformer” on page 3-5.)
18. Power down the ADVC by switching off all
MCB’s. Note that this should be done
whenever connecting or disconnecting the
control cable from the ADVC.
19. Fit the batteries if they are not already in
place.
Fitting the batteries with reverse
polarity will cause damage to the
electronic systems.

The ACR is type tested for Impulse Withstand
Voltages up to 125kV depending on the model.
See "Ratings and Specifications" - page 11-1
The surge arresters can be mounted on top of
the brackets or clamped to the side of the
brackets using the holes provided. Top holes are
12mm diameter, side holes are 16mm diameter.
In this way most types of surge arrester can be
accommodated.
When there is a possibility that lightning or
network switching conditions may produce peak
voltages in excess of 70% of the Impulse
Withstand Voltage, the manufacturer
recommends the use of suitably rated surge
arresters connected to each terminal of the
ACR.
The arresters should be mounted on the
mounting brackets supplied by the manufacturer
and earthed as described in Figure 7 (page 3-7)
and Figure 9 (page 3-9).
If the arresters are not mounted
close to the ACR the protection they
provide is significantly reduced.
Lightning induced damage to the ACR or ADVC
voids the warranty if surge arresters are not
fitted.
Mounting brackets are provided for surge
arresters on the ACR. This is illustrated in
Figure 6 (page 3-6) and Figure 8 (page 3-8).
Earthing
Figure 10 (page 3-10) shows the earthing
common to all installations.
This arrangement earths the ACR frame and the
surge arresters directly to earth through a main
earth bond consisting of a copper conductor of
70 sq. mm. Any surges will flow down this path.
Do not earth surge arresters by a
different path, doing this may
cause damage to the control
electronics or ACR. Also, any
antenna should be bonded to the
ACR or the main earth bond.
The control cubicle is connected to this main
earth bond by a tee-off. The control cubicle
LV Auxiliary
Power from
Mains
Where LV mains are connected to the control
cubicle to provide auxiliary power, the
connection must connect the neutral of the LV
system to a tee-off from the main earth bond as
shown in Figure 10 (page 3-10). A low voltage
surge arrester must also be fitted from the LV
phase connection to this tee-off.
This connection scheme bonds the LV and HV
earths and so protects the primary insulation of
the auxiliary supply transformer in the control
3-4
The user should check that phase/phase and
phase/earth clearance will be sufficient for their
particular surge arresters and line voltages. For
some types of side clamping surge arresters,
the phase/earth clearance may be insufficient at
the centre phase on the pole side at higher
voltages. In this case the surge arrester can be
mounted on the side of the power pole or an
increased clearance ACR mounting bracket
fitted.
Connections from the surge arresters to the
cable tails can be made by stripping off the
cable tail insulation and using a parallel or “T”
type clamp to make the connection to the cable
tail. The connection should be made far enough
up the tail so that phase/phase and phase/earth
clearances are maintained. It is good practice to
tape the joint using a bitumen or mastic tape, to
maintain the cabling system insulation.
electronics are internally protected from
potential differences which may occur between
the ACR frame and control cubicle frame whilst
surge currents are flowing down the main earth
bond. No other connections to earth from the
control cubicle are allowed since surge currents
will also flow in those paths. Follow this
arrangement on both conducting and insulating
power poles.
Keep the main earth bond physically separated
from the control cable, as they run down the
power pole, by the maximum spacing available
and at least 150mm.
cubicle when surge currents are flowing. Fit
additional LV surge arresters to all the other LV
phases (if they exist), to balance the supply for
other users connected to the LV system.
If local conditions or wiring rules prohibit
bonding the HV and LV systems in this way,
providing the auxiliary supply to the control
cubicle from the LV mains system is not
possible. Instead, use one of the alternative
arrangements detailed below.

Figure 11 (page 3-11) shows wiring and earthing
if a dedicated transformer is supplied by the
utility. Note that this should not be used to
supply any other equipment without consulting
the manufacturer to ensure that no hazard is
caused to the control cubicle electronics.
Figure 11 (page 3-11) shows that the
transformer and any steelwork is earthed to the
switchgear tank and that one side of the
transformer secondary is earthed to the earth
stud on the equipment panel inside the control
cubicle.

This is called an Integrated Auxiliary Supply.
which is pre-fitted with a cable gland through the
hole, secure the gland, connect the auxiliary
supply to the screw terminal block on the SCEM
and replace the compartment cover.
An external transformer is mounted on the pole
as shown in Figure 11 (page 3-11) which also
shows suggested HV connections. The
secondary of the external transformer connects
into the SCEM on the underside of the ACR. To
connect the transformer secondary, remove the
SCEM compartment cover plate, pass the cable
No additional earthing for Integrated Auxiliary
Supply is required in addition to the common
earthing shown in Figure 10 (page 3-10).
If the secondary of the VT is
earthed, electronics damage will
occur.

Equipment
It is highly advisable to connect a gas discharge
type of surge arrester in the antenna feed to the
radio. Failure to do so will result in loss of radio
and control electronics protection which could
lead to complete electronic failure due to
lightning activity.
A failure of this nature is not covered
by the products general warranty
arrangements.
A feed-through or bulkhead type arrester fitted
to the bottom of the control cubicle is ideal. If
fitted internally the surge arrester should be
earthed to an equipment panel mounting stud by
the shortest possible wire. Holes are provided
for a bulkhead surge arrester.
If a surge arrester is not fitted then the co-axial
earth screen should be earthed to the
equipment panel by the shortest possible wire.

therefore can only be connected to devices
inside the controller that are powered by the
controller radio supply, including modems,
optical isolators, and radios.
Use of serial ports to connect
directly to other devices outside
the controller can cause damage
and void warranty. If connections
to other devices are required then isolation
interfaces MUST be used.
An RS485 port has been provided to enable

V23 FSK
An in-built FSK modem provides half-duplex
V23 signalling at 1200 bits per second. This
interface is primarily designed for use with voice
frequency radio systems and provides additional
signals for this purpose.
The V23 connector is RJ45:
The Push to Talk (PTT) signal is used to key up
a radio transmitter. PTT is implemented using a
Field Effect Transistor (FET) with an on
resistance of 3.3 ohm. When PTT is asserted
the transistor is turned on and connects the PTT
signal to 0V.
A busy signal can be provided by the radio to
indicate receive channel busy. High level is
+2.0V to +3.3V, and low level is 0V to +0.5V.
The busy signal should be driven by an open
collector output or current limited to 10 mA.

Sealing &
Condensation
The ADVC is purposely designed for outdoor
pole mounted operation. The cubicle is vented
and insulated to minimise internal temperature
variation and maximise battery life.
Figure 24 (page B-2) shows the cubicle’s
dimensions.
All cubicle vents are screened against vermin
entry and the cubicle door is sealed with
replaceable foam tape.
Condensation can be expected to form under
some atmospheric conditions such as tropical
storms. However, condensation will be on metal
surfaces where it is of no consequence. The
water runs out in the same way as any other
water entering the cubicle. Condensation will
run out of the bottom or be dried by ventilation
and self heating.
Complete sealing against water entry under all
conditions is not expected e.g. during operation
in the rain. Instead, the design is such that if any
water does enter, it will run out of the bottom
without affecting the electrical or electronic
parts. The extensive use of stainless steel and
other corrosion proof materials ensures that the
presence of moisture has no detrimental effects.
All electronic modules are fully sealed and have
self heating.
Auxiliary
Power Source
The auxiliary supply is used to maintain charge
on the sealed lead-acid batteries that provide
standby power when auxiliary power is lost. The
controller monitors the status of both the
auxiliary and battery supplies.
A low power mode is activated when the
batteries are nearly exhausted due to loss of the
auxiliary supply. This mode minimises power
consumption while still maintaining basic
functionality.

U-Series Automatic Circuit Recloser
Operator
Interface/ Door
Assembly
The operator interface is provided by a separate
module - the basic display unit (BDU) with its
own processor. The BDU comprises the
electronics compartment cover, an operator
control panel (OCP) with LCD display, a
membrane keyboard and its controlling
microprocessor and the WSOS communications
port.
The BDU is attached to the door of the cubicle
and the operator control panel (OCP) can be
accessed through a hatch in the front door.
Under normal circumstances the hatch, which
can be latched open, is the usual access point
to the OCP.
When you are commissioning the ADVC, you
can lock the door open and swivel the OCP
open 90 degrees to the door. See Figure 18
(page 6-3). This allows you to gain access to the
OCP at the same time as commissioning the
equipment in the customer compartment.
The BDU plugs into Port E of the CAPE and
uses this port for its power and communications
Additionally, there is a Trip/Isolate connection to
the CAPE and the WSOS2 interface is
connected to an RS232 port.
WSOS Interface
Connect your PC serial port to the maintenance
port provided below the OCP. Use an RS232,
DB9 male to DB9 female, straight-through
cable.
Customer
Compartment
The compartment is fitted with a panel tray that
facilitates the mounting of your equipment e.g. a
radio or modem including any special interfaces.
See Figure 18 (page 6-3). The compartment has
a terminal block for the radio supply and power
for accessories such as an IOEX2. An
accessory heater can also be fitted which is
controlled by the PSU.

Description
The operator control panel (OCP) is the user
interface to the basic display unit (BDU) which is
mounted on the door of the ADVC.The OCP
consists of a four-line liquid crystal display
(LCD) and keypad with switches and light
emitting diodes (LEDs), which are used to select
and monitor the functionality of the ACR. The
OCP turns ON automatically when the hatch is
opened, or if the door is opened and the panel is
repositioned, and OFF when it is closed. The
OCP also turns OFF automatically if no keys are
pressed for 10 minutes. Pressing any key for 1
second will reactivate it.

ACR
Maintenance
Maintenance can be carried out using standard
electricians’ and mechanics’ tools.
Be careful to ensure that if working
on the ADVC with the door open in
heavy rain, water does not enter
the circuit breakers or general
power outlet.
No user maintenance of the ACR mechanism is
required.
A warning is displayed in the event log
when the remaining contact life reaches
20%.
The ACR should be returned to the
manufacturer for refurbishment if the
mechanical duty or breaking duty is exceeded.
This is checked by examining the remaining
contact life on the Operator Control Panel.
When the remaining contact life in any phase
approaches zero, the ACR has reached the end
of its life and must be replaced.
ADVC
Maintenance
Maintenance of the ADVC is required every five
years. The manufacturer recommends the work
described below.
Cleaning
Check for excessive dirt on the cubicle,
particularly the roof, and clean off.

Battery Care
The battery is predicted to provide good
performance for the recommended five year
service period. This is based on the battery
manufacturer's data. No battery warranty is
given by the manufacturer of the ADVC.
Once in service, batteries need little care.
Procedures for storage and other contingencies
are as follows:
„
they should be taken out, cycled and have
their capacity checked before being returned
to service.
To cycle a battery, discharge with a 10 Ohm 15
Watt resistor to a terminal voltage of 10V. Next,
recharge it with a voltage regulated DC supply
set to 13.8V. A 3A current limited supply is
appropriate.
Batteries should be stored at a temperature
of between 0°C to 30°C (32°F to 86°F) and
cycled every six months. Batteries should be
stored for a maximum of one year.
„ Batteries should be cycled prior to putting
into service if they have not been cycled
within three months. When shipped by the
manufacturer the batteries will have been
cycled within the previous 30 days.
„ If the batteries become exhausted in service
and are left for more than two weeks without
auxiliary supply being restored to the ADVC
Battery type, either standard or extended
temperature, is given in Appendix A (page A-1).
More information on the battery care is available
from the battery manufacturer.
Abnormal
Operating
Conditions
The operation of the capacitor charging inverter
can be affected under abnormal conditions such
as when the battery capacity is very low. The
following features are used to protect the ADVC
in this situation while still allowing the ACR to
keep operating.
Low Power
Mode
When the batteries are nearly exhausted, the
ADVC will change its capacitor charging mode
from normal to low power. In low power mode
the controller takes longer to charge the
capacitors and the radio supply is shut down. A
“Low Power Mode” event is logged whenever
this happens.
10-2
These batteries are capable of
supplying very high currents.
Always turn off the battery circuit
breaker before connecting or
disconnecting the batteries in the cubicle.
Never leave flying leads connected to the
battery.
Maintenance
Excess Close
Operations
When a trip occurs in low power mode, the
recloser will go to lockout if the capacitors
cannot be recharged quickly enough. Operator
close and trip operations can be performed, but
at a longer time interval than normal. If an
operator trip or close request is denied, a “Cap
Chrg” event will be logged.
During testing it is possible to carry out so many
trip/close operations that the capacitor charging
inverter shuts itself down before it overheats. It
takes more than 20 operations within a minute
to do this and is not going to happen while in
service (it only happens during excessive
testing).
Fault finding within the ADVC involves
determining whether the fault lies in the
electronic modules, the wiring or elsewhere. The
electronic modules are user replaceable items.
Other faults require the ADVC to be returned to
the factory.
„
If the System OK LED is not flashing, check
for loss of power. Check that the BDU is
plugged in to the CAPE. Check that the
battery circuit breaker is on and that full
battery voltage is present at the terminals.
Check the presence of aux supply on the
aux supply circuit breaker. Check that the
supply between the PSU and CAPE has not
been disconnected. Rectify if a problem is
discovered.
„
If power supply is present then attempt to go
on-line with WSOS to determine whether the
CAPE is functioning correctly. Replace the
CAPE or BDU as required.
„
If this does not rectify the problem then the
ADVC should be returned for factory repair.
To return to normal power mode, the auxiliary
supply must have been switched back on for a
minimum of 15 minutes, and the batteries may
have to be replaced.
When this happens the inverter shuts down for 5
minutes and a “Cap Excess Closes” event is
logged. During this time all trip/close requests
will be denied.
Fault Finding
ADVC Check
A suggested fault finding approach is as follows:
„
If the System OK LED on the OCP is
flashing then the CAPE microprocessor and
the BDU microprocessor are running. If the
OCP does not operate there is a problem
with the display itself and the BDU should be
replaced.
„ If the display is operating, check the
SYSTEM STATUS - SWITCHGEAR STATUS
page for an indication of any power supply
problems (Aux Supply Fail and/or Battery
OFF) which can be traced and rectified.
Replacement
of Electronic
Modules and
Upgrades
Electronic modules are user replaceable. Care
should be taken to avoid damage to the
modules while they are outside the cubicle and
replacement should only be carried out by
competent personnel.
PSU and CAPE firmware can be upgraded
through WSOS. Refer to the Operator Manual
for further details.
Removal of parts from modules will
void the warranty.
