IEC 60255-20 January 1, 1984 Electrical Relays Part 20: Protection (Protective) Systems A description is not available for this item. IEC 60255-1:2009 specifies common rules and requirements applicable to measuring relays and protection equipment including any combination of devices to form schemes for power system protection such as control, monitoring and process interface equipment in … This standard includes specification of the protection function, measurement characteristics and test methodologies. IEC 60255-27:2013 describes the product safety requirements for measuring relays and protection equipment having a rated a.c. voltage up to 1 000 V with a rated frequency up to 65 Hz, or a rated d.c. voltage up to 1 500 V. Above these limits, IEC 60664-1 is applicable for the determination of clearance, creepage distance and withstand test voltage. This first edition cancels and replaces IEC 60255-3, published in 1989.
