sir
what is the minimum IR value of 11 KV alternator?
Answer Posted / raghavendran.r
The thumb rule for IR value is that per kV of system it
must have atleast 1MOhm of insulation Resistance.
But We have a formula Which says
IR = Sys.kV + 1MOhm.
if System voltage is .415kV then Minimum Insulation
required is .415 + 1MOhm = 1.415MOhm.
