AbolishedElectrical relays - Part 22-7: Electrical disturbance tests for measuring relays and protection equipment - Power frequency immunity tests
电气继电器 第22-7部分：量度继电器和保护装置的电气骚扰试验-工频抗扰度试验
Application Summary AI generated
This standard specifies the power frequency immunity test requirements for measuring relays and protection equipment, ensuring these devices can withstand electrical disturbances at mains frequency (50 Hz or 60 Hz) without malfunction. It is applied in the testing and qualification of protective relays used in electrical power systems, such as those in substations, power plants, and industrial distribution networks. The standard helps verify the reliability of relay performance under common power frequency interference, such as ground faults or harmonic disturbances.
