Answer / ramaswamy venkatachalam

At the factory, it is tested by applying twice the voltage.
ie, 2U. If a dc kit is used, (2U)/sqrt(2) + 1 KV. Which is
a minimum of 48 kV. You can use 50 kV test kit for the same.

Convert the ac rms voltage to dc by dividing by sqrt(2) and
multiplying it by 2 and adding 1kV to it.

Answer / gunaskaran

for ac 0.8(2E+1) normally we r doing in ac if customer
asking we can do the dc for DC (2E+1*1.414)0.8 this 1.414
is AC to DC conversion this for site for factory we have to
applie 100% voltage

we specify current in case of feeder but in case of distributor voltage, why?
