Validity period of relay protection inspection report

A general rule of thumb would be to visually inspect every one to two years, secondary injection testing every one to three years, and primary injection every three to five years or on major changes. 15 seconds in its 30+ year life. But failure to operate as intended can result in extensive damage, extended power outages, and loss of life. NETA (InterNational Electrical Testing Association) reports show 12% Failure Rates on Protective Relays Tested. A. 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. Setting determines pick-up value/time. Tests are conducted by the manufacturer at manufacturer s works, and by the user at site during commissioning and periodic maintenance. This document also directs personnel to follow the utility procedures in the Protective Equipment Standard Test Procedures (PESTP) Manual and the. The NERC PRC-005-6 standards are designed to establish requirements for planning, designing, implementing, and maintaining protection and systems control within the power industry.
