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.
