Operation principle
SEMOD171791-5 v5
Broken conductor check (BRCPTOC, 46) detects a broken conductor condition by detecting the
asymmetry between currents in the three phases. The current-measuring elements continuously
measure the three-phase currents.
The current asymmetry signal output PICKUP is set on if:
