How to select the ratio of neutral ct? Is there any relation in between percentage impedance and neutral ct ratio ?
1 2054stand by earth fault protection (51G) for transformer rating 2000 kVA,Dyn11,33/0.400 V. LV NCT ratio and necessary resistor and metrosil values how to calculate
2186I 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.
