Voltage, current and resistance

Voltage and current

Only for resistance

Resistance and voltage

pure capacitance

high inductive and low capacitive reactance

high resistance and low inductive reactance

low inductive reactance and high capacitive reactance

fixed coil in parallel with the supply and moving coil in series with single phase motor

fixed coil across the motor and moving coil across the supply

fixed coil in series with motor and moving coil across the supply

Both fixed coil and moving coil in series with the motor

Potential transformers secondary terminals which are open should be insulated

Ground the secondary terminals on per circuit

The terminals of the potential transformer secondary have to be short circuited

After disconnecting, connect a low-resistance shunt between the terminal of the secondary

Earthing the secondary of CT

Short circuiting the terminals of the CT before disconnecting the ammeter

Switching a high resistance shunt between terminals of CT after disconnecting the ammeter

Disconnecting primary from supply
