Transient Voltage Surge Suppressors(TVSS)
for equipment, panel and motor protection,UPS's
applications are specifically
designed to provide long life, even
under the most adverse over-voltage
conditions.

The purpose of a TVSS is to eliminate or reduce damage to
data processing equipment
and other critical equipment by limiting transient (surge)
voltages and currents (surges) on
electrical circuits. These transients or surges may come
from inside a facility, or may be
injected into a facility from the outside.

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is onbserved the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?

There is no such thing as a Generator. All power generating devices are Alternator since both generate alternating current since this is the only way electrical power can be generated. In "generators" the alternating current is converted into DC inside the housing of the "generator" in order to give out DC Do you agree? If not please educate me. How else is DC generated if not like above?
