WebIn electrical circuits, current returns to its source. A current-based ground-fault relay may look for ground-fault current in one of two ways: 1.) Zero sequence. Here, the relay looks at the phase conductors to ensure that all current coming from the source returns on those same conductors. If some of the current is returning to the source ... WebFrom the GEC Guide, the relay F operating time is: From the SC studies, the average earth fault current at 0.164 s is 51.44 kA. As a PSM, this is 51,440/1200 = 42.9. From the relay characteristics, the relay operating time at a PSM of 42.9 and a TMS of 1 is 0.25 s. Therefore the required TMS is 0.164/0.25 = 0.66 ≪ 0.7. sasha banks cell phone number
