FIELD: electricity.
SUBSTANCE: invention relates to power industry and is intended for protection of transformers against short circuits in windings. The objective is solved by means of that the measuring converter is designed as a single coil of inductance which is placed at equal distance from each of the transformer core rods so that its longitudinal axis to be parallel to rods of this core. The use of such device consists in timely identification of short circuit in the transformer windings and its de-energizing, and consequently, in decrease of time and cost of post-fault repair.
EFFECT: improvement of reliability and sensitivity of the single-phase transformer winding fault protector.
