Series IMG
The Series IMG motor generator provides total electrical
isolation from voltage variations and electrical disturbances
on your normal utility source via the coupling between
motor and generator. The rugged industrial MG set can
tolerate a 40% drop from normal input voltage for 30 seconds
without affecting the load. While designed primarily as
a power conditioner, systems do provide ride-through from
5.5 to 8.0 cycles, depending on the size and type of system.
Series IMG motor generator systems are available as induction-sync
or synchronous-synchronous MG set configured in either
vertical or horizontal layouts. Systems are available
up to 2000kVA for low voltage applications up to 600V.
For medium voltage applications, please consult the factory.
The Series IMG motor generator was initially developed
for the United States Government in support of the critical
battle simulators used around the world. These power conditioner
systems have received awards as high as the Golden Eagle
Award for excellence. By making use of Motor Generator
technology, PS&C systems deliver quality power and
avoid the trouble spots.

Series IMG-RT
The Series IMG-RT Ride Thru Motor Generator integrates
state-of-the-art controls, a single-shaft motor generator
and a mechanical flywheel into a power conditioning system
that can deliver up to 5 seconds of ride-thru during an
interruption of power.
The typical induction-synchronous MG set delivers this
ride-thru with a maximum frequency drop at full load of
1%, or 0.6Hz on a 60Hz system. For sensitive applications
where no frequency variation is acceptable, a synchronous-synchronous
MG set is available. Series IMG-RT ride thru motor generator
systems are sized and customized to meet a wide range
of customer driven application criteria. MG sets are available
in size ranges up to 2500 kVA for low voltage applications
up to 600V. For medium voltage applications, please consult
the factory.

Series EPM - DC Energy Storage
Module
The Series EPM is a stand alone power module designed to
replace or supplement batteries in UPS systems. It is an
energy storage system that creates power by means of kinetic
energy conversion rather than the chemical reaction process
utilized by existing battery strings. PS&C’s Flywheel
topology is an extremely reliable source of emergency power
designed to support the DC voltage long enough for the standby
engine generator to start and be transferred on line, even
after the engine generator has been in service for a few
years. The Flywheel is driven by an induction motor through
a (VFD) variable frequency drive. The DC output is derived
from a three phase synchronous output converted via a rectifier.
As the standard construction is a two bearing, single shaft
machine, there are few serviceable components in the unit,
making maintenance requirements minor. PS&C’s
Series EPM combines the latest engineering methods with
“Brute Force”. The EPM offers the durability
and rigidness of a battery without the maintenance required
or the potential problems associated with them.
Design Features:
High efficiency induction motor
Brushless synchronous generator
Precision control variable frequency drive with constant
speed operating mode @ unity power factor
Performance will not decline over timeSix pulse three

Series MG
The Series MG is the most Robust industrial machine
available for isolating the utility from the load. Our
solution is ideal for any serious commercial/industrial
power users who have no need for the alternative of
a UPS system which brings additional problems and concerns
to Industrial customers. According to EPRI, power outages
are a result of sags or power losses in very short duration.
Statistics shown in a typical one month periods the
a power consumer will have the probability at 90% that
their business/factory will experience sags that will
drop the input voltage under 80% of rated nominal voltage.
This is very serious when we consider the potential
threat of an outage as the same EPRI stats are weighted
toward power interruptions in excess of 2 seconds.
The Series MG provides total electrical isolation from
spikes, brownouts, voltage fluctuations and electrical
disturbances on the commercial utility network. This
is accomplished via a coupling between the motor and
generator. The ride-through of the Series MG provides
power outage protection for short outages such as utility
re-closure operations.

| DYNAMIC
POWER FACTOR CORRECTION |
|
Series SC
The Synchronous Condenser (SC) dynamically provides power
factor correction without the use of static components.
As it is dynamic, the precise operation of the Synchronous
Condenser (SC) excitation field will produce the required
pf VAR needed to correct the power factor to the set level
or desired amount without switching transients. Also, as
it is a Dynamic device, there is no problem with harmonic
currents produces by (VFD's), dirty loads or static (solid
state) drives. The Synchronous Condenser (SC) uses rotary
technology which improves overall power quality by reducing
voltage transients and eliminating problems associated with
harmonic distortion which exist in all manufacturing processes.
How It Works
A Series SC is an unloaded or lightly loaded synchronous
machine that will deliver the required reactive power dynamically.
The SC is connected to the power line and is intentionally
run in an overexcited condition. The level of excitation
is dependent on the amount of power factor correction desired
and the amount of power factor sensed by the condenser controls.
The condenser will adjust the excitation level automatically
to maintain the power factor at the correct setting. Once
the Series SC is installed, it continuously monitors the
power factor and produces the right amount of VAR needed
to correct any power factor without switching transients
and is not troubled by harmonic currents produced by solid
state motor drives. The Series SC also helps overall power
quality by reducing voltage transients and by reducing the
problems associated with harmonic distortion found in many
manufacturing process. The Series SC is available from 100
kVAR to 10,000 kVAR modules, from 480 volts up to 15 KV.
Applying a synchronous condenser for power factor correction
provides many advantages with no risks. Correcting power
factor with a condenser is much smoother and will not adversely
affect a system loaded with current harmonics. The condenser
is a low impedance source and appears inductive to loads.
In addition the Series SC is easy to maintain (a simple
annual lubrication) and adapts easily to a plant’s
changing loads. (Dynamic Correction) The SC has many user
friendly features such as the automatic restart after power
loss. The SC also has a state-of-the-art integrated touch
screen display and control interface. The controls are designed
to be friendly and easily understood so that the user can
control the SC from this panel. The touch screen will display
voltage, current, power factor, and power information as
a minimum.
