Scope

This standard specifies the technical requirements, test methods, inspection rules, signs, labels, instructions for use, packaging, transportation, storage, supply completeness and quality of directional relays and power relays (hereinafter referred to as relays) with two input excitation quantities ensure. This standard applies to directional relays and power relays, but does not include impedance relays. The requirements on phase angle (direction) in this standard can be combined with the requirements on other characteristics (such as current) specified in the relevant electrical relay standards to apply to combined products such as "directional current relays". For special circumstances, supplementary requirements may be determined through negotiation between the manufacturer and the user or stipulated in product standards or enterprise standards. This standard applies only to new relays.
