WebYes. SFRA looks at the response of the complex RLC network inside a transformer. You can perform baseline or reference measurements on dry type transformers and compare results over the years. For dry type transformers, you need to be aware of the effect that ground capacitances can have on the traces. WebTransformer core grounds: a different path to maintaining insulation systems. BY JAMES WHITE, Shermco Industries, Inc. Power transformers are usually supplied with a ground from the core of the transformer to the tank (earth/ground). Smaller, dry-type transformers may not have this ground, but it is always used on larger transformers. WebAnswer: The following answer is based on AS/NZS3000 which is the Australasian Wiring Rules. For a 400Vac circuit, test at 1000Vdc and insulation resistance should exceed 1 megohm. For a 230Vac or 120Vac circuit, test at 500Vdc. Insulation resistance should excceed 1 megohm.
