Abstract: carrier-relaying equipment theco-ordinationofindividual relays isanimportant factor inthecorrect operation ofthe equipment. Itisthepurpose ofthis paper todescribe theoperating principles ofthevarious electronic relays employed intheall-electronic carrier-relaying equipment,andtopoint outthefeatures that havebeenincluded toobtain 1-cycle operation andwhichatthesametime guarantee co-ordination betweenterminals. Incompanion papers theneed forahigh-speed relaying equipment,' the over-all operating principles,2 andperformance evaluation' arepresented indetail. A directional-comparison relaying equipment mustperform thefollowing functions: detection ofabnormal system conditions, determination offault location, transmission ofblocking signal tothe remoteterminal, discrimination between short circuits andother abnormal system conditions suchaspowerswings and momentary powerreversals, andcontrol ofcircuit-breaker tripcurrent. These functions areprovided inagroupofelectronic relays whichoperate onthefollowing principles
