Introducing the BS EN IEC 63522-11:2025, a comprehensive standard that sets the benchmark for electrical relays, focusing on tests and measurements related to enclosure protection and the degree of protection. Protective relays and devices have been developed over 100 years ago to provide "last line" of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. The scope of TC 95 is the standardisation of measuring relays, protection equipment, and protection functions embedded in any equipment or systems used in various fields of electrical engineering covered by the IEC, including combinations of devices and functions that form schemes for power systems.
