35kV bus voltage too low
Cause/Remedy: See Power transmission Invalid mains: Supply voltage or DC bus voltage is too low. When single-phase-to-ground faults, ferroresonance, phase loss, or high-voltage fuse blowouts in voltage transformers (VTs) occur, the observed phenomena can be similar, but careful analysis reveals distinct differences. The substation and SCADA system will issue signals such as “35kV busbar. BUS voltage fault: BUS overvoltage or the difference between the positive and negative BUS voltage exceeds. Check the frequency of the fault. Thanks Engr Raja Haroon Rasheed Authentication Failed. Authentication Ticket. 35 kV switchgear supports sub-transmission and industrial feeders that need higher insulation and fault duty. Voltage/BIL: 35 kV class, typical BIL 170 kV. Short-circuit: 25–40 kA short-time withstand common; confirm with system fault. The metal-enclosed non-segregated phase bus runs are designed for 635 V, 5 kV, 15 kV, 27 kV and 38 kV service in accordance with ANSI C37. Available ratings are shown in Table 11.
