On-site prevention measures for relay protection
The standard DL/T 2533-2022, published on November 4, 2022 and implemented since May 4, 2023, sets out to define the safety measures for on-site work involving relay protection and automatic security devices in power plants. However, to ensure reliable operation, it is important to. Ensuring that protection systems operate reliably is crucial, and a good preventive maintenance program ensures that protection and relay systems function properly without causing additional problems. On such products, intensive testing is desired to prove its characteristics and to gain information about it. (ii) On relay types which have been used earlier, only minimum necessary checks should. ERS provides turnkey solutions for maintaining and testing electromechanical, solid-state, and microprocessor-based relays, as well as IEC 61850 IEDs, relay panels, and distributed protection systems. -
