FIELD: electric power industry.
SUBSTANCE: measuring transducer and the reacting element are implemented in the form of a reed switch and, as magnetic field concentrators, rods made of ferromagnetic material, fixed to form a common longitudinal axis and located relative to the transformer so that the longitudinal axis is parallel to the axes of the transformer core rods and is at the same distance from them.
EFFECT: increasing the power supplied by the measuring transducer and improving reliability of protection of a single-phase transformer.
