Broken conductor check BRCPTOC

Identification

Function description
Broken conductor check

Functionality

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