field and began manufacturing to fill those needs
 Full Dielectric Testing Lab- Rubber goods, Hot
Line Tools, Boom Trucks
 Revenue Protection Consulting Group- Assist

Power Quality- Sources of Problems



Harmonic distortion
Continuous or sporadic distortions of the 60-hertz (Hz) voltage sine
waveform, usually caused by microprocessor based loads in the building
such as computer power supplies, lighting ballasts, and electronic
adjustable speed drives. Harmonics can also be transmitted from an energy
user down the block. These can cause telecommunications or computer
interference; overheating in motors, transformers, or neutral conductors;
decreased motor performance; deterioration of power-factor correction
capacitors; or erratic operation of breakers, fuses, and relays.
Interruption, momentary
A very short loss of utility power that lasts up to 2 seconds, usually caused
by the utility switching operations to isolate a nearby electrical problem.
Interruption, temporary
A loss of utility power lasting from 2 seconds to 2 minutes, caused by a
nearby short circuit due to something like animals, wet insulators, or
accidents. Corrected by automated utility switching.
Power Quality- Sources of Problems



Long-term outage
A loss of utility power lasting more than 2 minutes due to major local,
area, or regional electrical events.
Noise
Sporadic voltage changes consisting of frequencies higher than the
normal 60-Hz power frequency due to any number of causes,
including arc welders, loose wiring, and nearby radio and TV
transmitters.
Sag
A short-term decrease in voltage lasting anywhere from milliseconds
up to a few seconds. Sags starve a machine of the electricity it needs to
function, causing computer crashes or equipment lock-ups. Usually
caused by equipment start-up-such as elevators, heating and airconditioning equipment, compressors, and copy machines-or nearby
short circuits on the utility system.
Power Quality- Sources of Problems




Spike
A very brief (nanoseconds to milliseconds) change in voltage ranging from
tens to thousands of volts. Can be produced by utility and customer
equipment operations, nearby lightning strikes, falling tree limbs on power
lines, and even static discharges.
Surge
A short-term increase in voltage, lasting up to a few seconds. They are due
either to customer equipment operation, such as air conditioners or motors
switching on and off, or to utility activities, such as capacitor switching.
Transient
A sudden momentary change in voltage. Also called a spike.
Undervoltage
A decrease in voltage lasting longer than a few seconds. Usually due to
undersized wiring at the facility but can also be caused by overloaded utility
circuits and result in brownouts.
Power Quality- Why do customers
call? What are we really looking for?



Lights dim when several appliances are in use or as they
are turned on. (hair dryers, toaster oven, TV, stereo,
computer)
Lights work, but appliances do not work properly
(toaster oven doesn’t heat, hair dryer runs slow, etc.)
We are looking for service problems…on the Utility
Side (examples: transformer to meter cable
faults/connections) or Customers Side (examples:
internal electrical circuit, faulty wiring, circuit
breaker/fuse).
Power Quality Testers


The Super Beast and Mega Beast are conductor
testers used to apply an Amp load on 120/240
volt service to determine if there is an conductor
or neutral problem.
Eliminates the need for homeowner being
present during testing. One utility employee can
perform a test at the meter socket and
immediately determine the source of problems.
First things First



The following tutorial is
a factory simulated
model and results for
individual utilities may
vary.
Always wear proper
safety equipment when
operating the Mega
Beast.
Make sure all
connections are secure.
Getting Started

Remove the KWH meter
and inspect base for loose
connections or other issues.

With the Mega Beast 100
Amp breaker in the off
position (de-energized),
hook up the alligator clips as
shown. First place the
Green Neutral, then place
Black on left, Red on Right.
Voltage

When the alligator clips
are secured in place, flip
the 100 Amp breaker to
“ON” and the voltages
between each conductor
and the neutral will be
displayed on the digital
meters. The 112 V
shown to the right
should be 120V +/- 5%.

Remember the displayed
pictures are factory
simulations and not
indicative of actual field
voltages.
Applying a load to the left conductor

Turn the switch to the
left and start by applying
20 Amps by turning on
one of the four toggle
switches (no order
necessary). You may add
an additional 20 Amp
load as needed, up to 80
Amps. In the following
picture there is no
problem with the left
meter only dropping 1V.
Applying a load to the left conductor

This photo shows a
partially open left
conductor with the left
meter dipping
significantly and the right
meter only dropping a
volt or two.
Applying a load to the left conductor

Here we have a fully
open left conductor.
The left meter goes
blank and the right meter
remains close to the
original voltage.
Applying a load to the left conductor

The photo on the right
shows us a partially open
neutral. With the load
applied to the left, the
left meter decreases
significantly and the right
meter increases. If you
move the switch to the
right you will see the
voltages reversed.
A full open neutral

A full open neutral is
shown here to the right.
Whether you have the
load applied to the left or
right conductor the
meter readings will be
the same with one close
to 240V and the other
blank.
Applying a load to the right
conductor

The right meter drops
one or two volts and the
left meter doesn’t drop
or drops very little. The
more load you apply the
more the voltage
readings will decrease. If
no major change in
voltage then the utility
side of the meter is OK.
Applying a load to the right
conductor

This photo shows a
partially open right
conductor with the right
meter dipping
significantly and the left
meter only dropping a
volt or two.
Applying a load to the right
conductor

Here we have a fully
open right conductor.
The right meter goes
blank and the left meter
remains close to the
original voltage.
Applying a load to the right
conductor

The photo on the right
shows us a partially open
neutral. With the load
applied to the right, the
right meter decreases
significantly and the left
meter increases. If you
move the switch to the
left you will see the
voltages reversed.
Referencing the field guide on back
panel

Remember, if you take
the Mega Beast out in
the field and haven’t
used it before or it has
been awhile, please read
the field instruction
guide on the back panel
for a quick review.
Finishing Note



Please remember to wear your safety clothing
and rubber protective gear when using the Mega
Beast.
The Mega Beast is for use on 120V service only.
If you have any questions or need any assistance
using the Mega Beast, please give us a call at 1800-684-9844.
