Abstract
Overview
IEC 60255-127:2010 is an international standard established by the International Electrotechnical Commission (IEC) that specifies minimum functional requirements for overvoltage and undervoltage protection relays. This standard focuses on measuring relays and protection equipment to ensure reliable and accurate voltage protection functions in electrical systems. It provides detailed specifications regarding the protection functions, measurement characteristics, time delay characteristics, and testing methodologies critical to the effective performance of over/under voltage relays.
