FIELD: electricity.
SUBSTANCE: current is measured via two connected in series windings and capacitor having fixed capacitance upon their connection to the voltage sources of increased frequency. Measurement is performed upon any combination of windings. Further based on measurement results the conclusion is made on presence of turn-to-turn short circuits.
EFFECT: possibility of diagnostics of turn-to-turn failures at an early stage of development.
