Question
Dear ZZ

Can High voltage Tester instrument check and test power and distribution Transformers which are live in use for power transmission and power distribution purposes?.

Thanks
Prashant

Answer
Power transformer must be pulled out of service for testing.  A substitute transformer is usually put into service whilst the suspected unit is put under test off-line.

This is required because the tester cannot compete with the power distribution lines.
