| Riassunto: | Title screen The article presents the disadvantages of traditional and some new electric protections of powerful electric motors. It is proposed to eliminate these drawbacks by constructing phase-sensitive protection that does not use current transformers, with a majority circuit and functional diagnostics. The methods of choosing protection settings are given. The algorithm of its functioning, implementation and operation in various modes is considered.The construction for mounting to protect the blocks near the conductors of the motor phases is presented.
