Make sure there is no voltage measured between line of secondary and neutral of primary. I.e. neutral of primary and secondary are not connected by any means.

Run the test signal through a small isolation transformer.


Can an isolating transformer have a center earth tap?

I suppose it could, but then it wouldn't be purely an isolation transformer. It would then be a isolation and either step up or step down transformer.

What is the difference between an isolation transformer and distribution transformer?

in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthedAnswerAn isolation transformer is a 1:1 ratio transformer; its function is to electrically isolate the secondary side from the primary side without changing the voltage. An example of an isolation transformer is the one used in a shaver socket.A distribution transformer is a step-down transformer, used within the electricity network's distribution system. An example of distribution transformer is a pole-mounted transformer, supplying low voltage to residences.(Of course, all mutual transformers provide electrical isolation between primary and secondary.)

What are the voaltg in isolation transformer?

The function of an isolation transformer is to electrically-isolate the secondary circuit from the primary circuit, without changing the voltage levels. So, its secondary voltage will be the same as the primary voltage.
