FIELD: electrical engineering.
SUBSTANCE: invention relates to the testing of transformers. Essence: the transformer testator contains an inverter converter, a L-shaped reactor-capacitor filter, connected in series, output transformer, capacitor, protective device in the form of a fuse or circuit breaker. Capacitor is connected in parallel with the primary winding of the output transformer. Between the filter output and the transformer, a protective device is included.
EFFECT: higher reliability.
