Microprocessor-based relay protection tester characteristic and function testing

Microprocessor-based relay protection tester characteristic and function testing

In order to verify the proper operation of complex multifunctional microprocessor-based protection devices (MPD) at their inspection, start-up after repairs, or during periodic tests, they should be tested for proper operation at several of the most critical preset. Since the basic function of a protection relay is to correctly function under abnormal. The first relays were Electromechanical (EM): machines with moving parts actuated by coils connected to current and voltage sources. These required regular testing, adjustments and maintenance to ensure continued functioning.

Relay Protection Field Verification Procedure

Relay Protection Field Verification Procedure

One approach to test the total protection system is to use primary injection techniques (see appendix H) that trigger protective relays and lockout relay, trip circuit breakers, and initiate annunciations and indications. The testing and verification of protection devices and arrangements introduces a number of issues. Protective circuit functional testing, including lockout relay testing, must take place immediately upon installation, every 2 years thereafter, and upon any change in wiring. The procedure depends on the relay type (electromechanical, static, or digital/microprocessor-based), but the general steps include:.
