METHOD AND APPARATUS FOR TESTING A TRANSFORMER
First Claim
1. Method for testing a transformer, comprising the stepsa) emulating the transformer by means of an equivalent circuit,b) applying a test signal to the transformer,c) detecting a test response of the transformer in dependence on the test signal,d) automatically determining an equivalent-circuit-related accuracy of the transformer on the basis of the test response, ande) automatically determining an operating-condition-related accuracy of the transformer from the equivalent-circuit-related accuracy.

Abstract
For testing a transformer (20) the transformer (20) is emulated by an equivalent circuit (30) and an accuracy of the transformer (20) relative to the equivalent circuit (30) is determined by evaluating a test response of the transformer (20) and is then automatically converted to an operating condition-related accuracy of the transformer (20).

21. Device for testing a transformer, comprising
a test signal source for generating a test signal which is to be applied to the transformer, a test response detecting device for detecting a test response of the transformer in dependence on the test signal, and an evaluation device which is so configured that it emulates the transformer by an equivalent circuit and, on the basis of the test response, automatically determines an equivalent-circuit-related accuracy of the transformer and converts that accuracy into an operating-condition-related accuracy of the transformer.
