FIELD: electricity.
SUBSTANCE: summary of the invention: detection of turn-to-turn short circuits is performed in a loaded mode by the current magnitude in the coil winding when the constant voltage is applied to it. Together with applying the constant voltage high voltage pulses are applied to the winding. In 1 minute the supply of high voltage pulses is cut off and the current magnitude is measured in the winding.
EFFECT: increased rate of turn-to-turn fault detection.
