35KV bus voltage is excessive

35KV bus voltage is excessive

The DC bus voltage has exceeded the programmed high voltage limit, typically above 110% of rated value. 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. DC Bus overvoltage generates a hardware interrupt at 480V. DC Bus Overvoltage Fault (Firmware,Positive & negative) The DC bus voltage is sampled in A/D interrupt (4-point running average). Auto. When a 35 kV distribution network has the problem of insufficient reactive power, the input of a shunt reactor is a common compensation method. This condition trigge...
