  • How often should relay protection systems undergo a comprehensive inspection

    How often should relay protection systems undergo a comprehensive inspection

    A full visual, mechanical, and electrical test should be performed every 24 months for electromechanical and solid-state relays, and every 36 months for microprocessor relays. Look over the relays and their cases for any physical damage, and check for foreign objects or debris. For microprocessor units, make sure the relay is displaying the correct date and time. Secondary injection testing is typically conducted every 1–2 years. Is secondary injection enough for routine maintenance?A comprehensive relay protection system maintenance checklist ensures that every relay, control circuit, and protection scheme receives the verification it needs to perform reliably under fault conditions. Rare operation, critical function: Protective relays may operate only once every several. Protective Relay Testing – Overview: To ensure reliable operation of protection systems, protective devices must undergo complete calibration and inspection at least once a year.
