The common power conducting wires or bars to which all power sources
within the power system are connected through their individual circuit
A bus from which all the available power sources are disconnected.
To remove voltage from a circuit or device in order to deactivate it.
Paralleling mode that allows slight fluctuations in frequency so that lagging
generator set can match frequency of companion generator.
Electromagnetic interference is any electromagnetic disturbance that
interrupts, obstructs or other wise degrades or limits the effective
performance of electronics and electrical equipment as a result of spurious
emissions and responses.
To apply voltage to a circuit or device in order to activate it.
DC voltage applied from the voltage regulator to the generator exciter field
Generator overload condition
Load greater than the load for which the system or mechanism was intended.
For TQGs, overload is defined as the condition when current in all three
phases exceeds 100% of rated current or when current in a single phase
exceeds 130% of rated current.
Ground fault circuit interrupter (GFCI)
A device intended for the protection of personnel that functions to de-
energize a circuit or portion thereof within an established period of time when
a current to ground exceeds some predetermined value that is less than that
required to operate the overcurrent protection device of the supply circuit.
The TQG convenience receptacle is protected by a GFCI.
The generator that is being connected to the bus.
Kilovolt. One kilovolt equals 1000 volts.
Kilovolt amperes reactive. Measure of reactive power.
Kilovolt amperes reactive hours. Measure of reactive power over time.
Kilowatt. One kilowatt equals 1000 watts. Measure of real power.
Common power conducting wires or bars to which all generator set loads are
connected through their individual circuit breakers.
Any current in excess of the rated current of equipment. The condition may
result from overload, short circuit, or ground fault.
The procedure for synchronizing and connecting two or more generator sets
to a common load bus.
in parallel. For the TQGs, reverse shutdown power occurs when reverse
power exceeds 17% of rated value.
