Abstract
A mobile transformer test device (10) for testing a power transformer (40) has connectors (12) for the detachable connection of the transformer test device (10) to the power transformer (40). The transformer test device (10) has a source (5) for generating a test signal. The mobile transformer test device (10) has an evaluation circuit (6) for determining, based on the test signal and a test response of the power transformer (40), information regarding a B-H curve (50, 60) of the power transformer (40).
