FIELD: electricity.
SUBSTANCE: invention relates to tests of a load tap changer of a transformer. Essence: a test signal that is fed into the transformer winding and the load tap changer is generated. Tap changer is actuated multiple times to change the transformation ratio during each actuation. Curve of the electrical measured value of the transformer in time during the actuation stage of the tap changer, depending on the test signal is constructed. Curves are automatically displayed with time overlapping.
EFFECT: technical result: simplification.
