over current-a)instantaneous, idld,thermal earth fault,
under votage.

Answer / romeo

in addition, differential relays for current and voltage
are necessities also to monitor considerable leakage of
current and difference in voltage (in case of two leg
switchgear for a make and break design) to a magnitude that
will activate tripping action or prevent closing of the bus
tie.

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?
