High swr protection circuit

WebOct 8, 2024 · A protection relay is usually required to trip a circuit breaker (CB). The power required by the trip coil of the CB may range from 50 W for a small distribution CB to 3000 W for a large EHV CB. Where such appreciable current-carrying capacity is required, interposing contactor type elements will normally be used. Webstart [285 TechConnect Radio Club -- NAØTC]
