DIRECTIONAL POWER RELAY BASED ON TRANSFORMERS WITH ROTARY MAGNETIC FIELD Russian patent published in 2011 - IPC H02H3/38 H01F29/14 

Abstract RU 2435269 C2

FIELD: electricity.

SUBSTANCE: directional power relay comprises a transformer reactor, a transformer, the first and the second single-phase rectifiers, a barrier filter, a smoothing capacitor and a zero indicator, at the same time the input of the first single-phase rectifier is connected to the transformer reactor outlet, the input of the second single-phase rectifier is connected to the transformer outlet, the inlet of the barrier filter is connected to the outlet of the first single-phase rectifier, the zero indicator is connected to the outlet of the barrier filter and to the outlet of the second single-phase rectifier, the smoothing capacitor is connected in parallel to the zero indicator, the transformer reactor is made with a rotary magnetic field and comprises two groups of multi-phase secondary windings, the transformer is also made with a rotary magnetic field and comprises two groups of multiphase secondary windings, at the same time the first and the second single-phase rectifiers are made as multi-phased.

EFFECT: increased efficiency and accuracy of relay operation.
