Broken Conductor (46BC)

A typical unbalanced fault that can occur on the system is an open circuit fault. This

fault can arise from broken conductor, discrepancy of one switchgear poles position

or blowing of a fuse.

MiCOM P122, P123 and P127 relays are able to measure the ratio of negative to

positive sequence current (I2/I1). This fully programmable function allows more

sensitivity and stability than pure negative sequence measurement
