g) BROKEN CONDUCTOR DETECTION
PATH: SETTINGS  CONTROL ELEMENTS  MONITORING ELEMENTS  BROKEN CONDUCTOR 1(2)
Two broken conductor detection elements are provided.
The broken conductor function will detect a transmission line broken conductor condition or a single-pole breaker malfunc-
tion condition through checking the phase current input signals and the I_2 / I_1 ratio. The intention of this function is to
detect a single-phase broken conductor only. As such two-phase or three-phase broken conductors cannot be detected.
