What is BS EN IEC 60255-181‒ Requirements for frequency protection about?
BS EN IEC 60255-181 is a part of the multi-series standard that covers measuring relays and protection equipment. BS EN IEC 60255-181 specifies the minimum requirements for functional and performance evaluation of frequency protection. It defines a procedure to explain the documentation and publishing of the performance test results. BS EN IEC 60255-181 covers the functions based on frequency measurement or rate of change of frequency measurements and frequency protection where additional blocking elements are used. BS EN IEC 60255-181 defines the influencing factors that affect the accuracy under steady-state conditions and performance characteristics during dynamic conditions. It includes the test methodologies for verifying performance characteristics and accuracy.
