Pre-shipment acceptance testing of relay protection devices
A comprehensive testing program should simulate fault and normal operating conditions of the relay. Acceptance testing, commissioning, and startup will include control power tests, current transformer and potential transformer tests, and any other device testing . The testing and verification of relay protection devices can be divided into four groups: Type tests are needed to prove that a protection relay meets the claimed specification and follows all relevant standards. Since the basic function of a protection relay is to correctly function under abnormal. Installation tests are field tests to determine that the protection operates correctly in actual service. This SWP should be interpreted in conjunction with Standard for Substation Protection (V1.
