8.2.
Self powering
8.2.1. Single phase minimum self-powering checking
Adjust the Sverker current generator with HOLD 0.2xIn, and suddenly, inject it to the relay,
as it would happened in real situation when circuit breaker is close, powering network line.
8.2.2. Three phase minimum self-powering checking
Adjust the Sverker current generator with HOLD 0.1xIn, and suddenly, inject it to the relay,
as it would happened in real situation when circuit breaker is close, powering network line.
8.2.3. Verification of Leds/Signalling Outputs/LCD in self-powering conditions
Adjust the Sverker current generator with HOLD 0.2 xIn, and suddenly, inject it to the
relay, as it would happened in real situation when circuit breaker is close, powering
network line. Once the relay is switched up, increase current injection until 0.35xIn
isreached. At this value, the Leds and LCD should be switched on:
