SINOPSIS DEL LIBRO

<p>Power system protection systems have three basic components: Instrument transformers, Relays, Circuit breakers<br><br>The function of the CT is to reproduce in its secondary winding a current I' that is proportional to the primary current I. The CT converts primary currents in the kiloamp range to secondary currents in the 0?5 ampere range for convenience of measurement.<br><br>The function of the relay is to discriminate between normal operat...Seguir leyendo
