Broken conductor check BRCPTOC - 46
7.13.1 Introduction
Conventional protection functions can not detect the broken conductor condition.
Broken conductor check (BRCPTOC, 46) function, consisting of continuous current
unsymmetrical check on the line where the IED is connected will give alarm or trip at
detecting broken conductors.
