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.
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
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.

A: there is no formula the gain of the amp is just reduced by the transformer turn ratio minus efficiency or loss. the transformer is for isolation and impedance matching

Run the test signal through a small isolation transformer.

220-230vac = -10
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.)
You will have a 1:1 ratio isolation transformer.
why need dielectric test for transformer
first is isolation test with 4.5 kv or above as per the custumer had asked between primary and secondary.also to find the leakege inductance its test is required for both primary and secondary.find the megnetising inductance between two winding(or say coupling )
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.
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
