All transformers are subjected to follow the Routine tests based on the operational performance requirement of individual unit, i.e. as listed below;
Insulation resistance Test.
Winding resistance Test.
Turns Ration / Voltage ratio Test
Polarity / Vector group Test.
No-load losses and current Test.
Short-circuit impedance and load loss Test.
Continuity Test.
Magnetizing Current Test.
Magnetic Balance Test.
High Voltage Test.
Dielectric tests (Separate source AC voltage/ Induced overvoltage/ Lightning impulse tests).
Test on On-load tap changers, where appropriate.
Routine tests of transformer include
