Home / Test Standards for Switch Relay Protection
IEC 60255-1:2022 specifies common rules and requirements applicable to measuring relays and protection equipment, including any combination of equipment to form a distributed protection scheme for power system protection such as control, monitoring and process interface equipment . Since the basic function of a protection relay is to correctly function under abnormal. Protective relays and devices have been developed over 100 years ago to provide "last line" of defense for the electrical systems.
These cover the mechanical performance of relay such as tendency to vibrate, effect of shocks, balancing of rotor, endurance tests, deviability of springs etc. Special test equipment is necessary to
