The system for control and protection of electrical machine from emergency operation

Abstract

The article considers establishing of a system for control and protection of an electrical machine from emergency operation using stator winding machine as a sensor and its resonance characteristics. The authors suggest a structural-functional diagram of such a device and show experimental data on the use of the system for an asynchronous motor. Studies have shown that the sensor is winding machine insulation.
