Abstract :
Protecting the motor is obviously the most important task of protection relays regardless of the technology that they are based on. Microprocessor-based relays are capable of processing the measured data (i.e., current, voltage, and status indication) in many different ways. Registered data in the relay can be sent through a communication network to the operation/engineering headquarters for continuous monitoring or fault analysis. In addition to being used for motor protection, relays provide useful information to other departments (maintenance, planning, etc.).
