Boss, for AL cable 1sqmm take nearly 1-1.5A current, if the conductor size goes on increases to a large extent then take it has 1A. But there's no large variations from meter to meter... Ex: 5m cable and 15m cable there is no loading current variation, it varying in long cables due to voltage drop..

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?

v=I*R, i.e V is directly proportional to I. now P=V*I. so V=P/I. thus v is inversely proportional to I. so what is the correct one? If both are correct than for which kind of condition this 2 differ

FOR 16/20 MVA 132/33 KV ONAN/ONAF TYPE TRANSFORMER IT IS DESIGNED FOR 16 MVA WITH ONAN CONDITION.IT BECOMES 20 MVA UNDER ONAF CONDITION.LOAD LOSS IS GUARANTEED FOR 65KW AT 20 MVA AND % IMPEDANCE 13.75. PLEASE TELL US AT WHAT LOAD LOSS AND % IMPEDANCE IT SHOULD BE DESIGNED FOR 16 MVA AND WHAT WILL BE ITS EFFICIENCY AT 20 MVA?
