GB/T 14598.151-2012
ActiveMeasuring relays and protection equipment - Part 151: Functional requirements for over/under current protection
量度继电器和保护装置 第151部分：过/欠电流保护功能要求
Application Summary AI generated
This standard specifies the functional requirements, performance criteria, and testing methods for overcurrent and undercurrent protection relays used in electrical power systems. It is applied by manufacturers and engineers to ensure reliable operation of protection equipment in substations, industrial facilities, and power distribution networks, particularly for detecting abnormal current conditions and initiating circuit breaker tripping. The standard also defines accuracy, resetting, and time-delay characteristics for both phase and earth fault protection functions.
