Three-phase induction motors are the most common and frequently encountered machines in the industry

Modern numerical motor relay protection technology must be sufficient to meet the protection requirements of any of the vast range of motor designs. A motor protection relay providing sufficient protection will have the following set of characteristics such as extended start relay protection, loss-of-load relay protection, number of starts limitation, stalling relay protection, short circuit relay protection, thermal relay protection, Earth fault relay protection, negative sequence current detection, winding RTD measurement/trip, under-voltage relay protection, auxiliary supply supervision, …
