Answer / sparta

in 3 phase four system , only unbalance current flow
through neutral wire , which in mili ampear.

Answer / k.prakashchandra

That is in case of 3 phase supply ,as only the unbalanced
current flows through the neutral

Answer / rama kranthi sri

it is because the neutral wire carries only the unbalanced
current. it doesnt carry the full load current. so, the
neutral wire is thinner when compared to phase wires in
three phase.

I want to ask a question which i faced during testing of Capacitive Voltage Transformer in AIS. We have measured the C1 , C2 individually , but when we start to measure the total C1+C2 , the testing equipment shuts down and says low loading. Kindly is it possible to find the total capacitance by using measuring device. kindly briefly explain the procedure.
