Answer Posted / vijaya kumar.m
Power factor means Cosine angle between Voltage and Current
so cosine rang is in between -1 to +1 so power factor unity
means one(1)
For only inductive load current lags voltage behind 90deg
For only capacitve load voltage lag current behind 90deg
For only Resistive load current and voltage both are same
phase

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
