IEC 60255-5 Electrical Relays - Part 5: Insulation Coordination for Measuring Relays and Protection Equipment - Requirements and Tests - Withdrawn

IEC 60255-5 lays down general requirements for the insulation coordination of measuring relays and protection equipment. Gives guidance for the selection of clearances and creepage distances and other aspects related to the insulation of measuring relays and protection equipment; specifies requirements for voltage tests and insulation resistance measurement.

This standard also applies to associated auxiliary devices such as shunts, series resistors, transformers, etc., used and tested together with measuring relays and protection equipment as mentioned above, except where the devices are covered by other IEC publications, for example communication interfaces.

Note: this standard has been replaced by IEC 60255-27
