The common power conducting wires or bars to which all power
sources within the power system are connected through their
individual circuit breakers.
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
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.
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.
Paralleling mode that requires precise matching of frequency for
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.
