Measurement procedure and circuit for a power network circuit breaker, for detecting when a load is switched on again and re- connecting a network so power can be drawn, based on a change in applied voltage or supplied current
Measurement procedure and circuit for a power network circuit breaker, for detecting when a load is switched on again and re- connecting a network so power can be drawn, based on a change in applied voltage or supplied current
Procedure involves measurement of a relative change of current flowing through, or voltage applied to, a circuit breaker, which is independent from the absolute value of voltage or current at the beginning of the change.
