Sets out the performance conditions for the relays and parameters whose values the manufacturer has to state. Suggests ways to present the properties and performance of these relays. Relevant to relays designed to discover faults, especially in a.c. generators, motors and transformers. Does not apply, however, to relays designed for busbar protection, or to current differential relays.
