A group of machines (wind turbines) connected with 33KV feeder and each machines are having individual VCB. The 33KV feeder connected with 110KV/33KV substation. The 33KV feeder tripped by over current at Substation and fault recorded at Substation as OC-R&Y phase. Same time the group of machines VCB tripped by over voltage, the fault recorded voltage was above 66KV by numerical Under/Over voltage relay. While grid drop time, this much of voltage hike is possible?
