Answer Posted / kapil
The regulation of transformer is same as it's percentage
impedance. this means the secondary voltage will drop @ 5%
for a transformer having 5% impedance. to compensate this
internal voltge drop we select nominal tap setting to 433
v. if you keep nominal tap for 415 V, we can not properly
utilize tapping range as 5% is internal drop at full load.

we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
