What is the exact load current needed for a place which has
100nos of bulb of each 100w?
Answer Posted / karthik
for single phase, P=VIcos0.
When P=100W, Icos0=P/V.
Icos0=100/230.
for 100 nos, Icos0=100*100/230
=43.48A
if cos0=0.9, I=48.3A

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 observed 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?
