GE Multilin L90 Line Current Differential System 5-2795 SETTINGS 5.7 CONTROL ELEMENTS5Figure 5–152: OPEN POLE DETECTOR LOGIC (Sheet 2 of 2)i) BROKEN CONDUCTOR DETECTIONPATH: 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 todetect a single-phase broken conductor only. As such two-phase or three-phase broken conductors cannot be detected.
