how to find insulation resistance of a generator(11kv) by
theoritical formula??
Answer / raghavendran.r
Ins. Resistance = Sys.Voltage + 1
so IR in thsi case will be = 11kV + 1
So IR = 12MOhm.
A thumb rule is that Per kV of Sys Voltage must have 1MOhm
of Insulation resistance.

what is reactive power?
what are earthing material
How many percent of power are not being registered if we bypass one side of the meter base terminal using #8 cu wire on 1-phase kwhr meter.
need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
sir, what is the importance of Fault MVA. how to calculate fault mva of 33kv substation connected by 6.5 km line(single circuit with equal spacing) with 110/11kv transformer in 110kv susbstation.the fault mva on 11 kv bus in 110kv susbstation is 208mva.
