Measuring relays and protection equipment - Functional requirements for over/under voltage protection Ingestion-build-258901 6 Verification of safety and1 Scope This part of IEC 60255 specifies minimum requirements for over under voltage relays. The standard includes specification of the protection function, measurement characteristics and time delay characteristics. This standard defines the influencing factors that affect the accuracy under steady state conditions and performance characteristics during dynamic conditions. The test methodologies for verifying performance characteristics and accuracy
