Answer / deepak

Phase voltage & phase current are between the phase and neutral while the line voltage n current are b/w the line.

Answer / rajamanickam

Phase voltage; potential difference of (phase to neutral) called phase voltage.
Phase current; total flow of current in one phase winding, called the phase current
Line voltage; potential differences of two phases (phase to phase) called the line voltage.
Line current; total flow of current in two phase (R B,R Y) winding called the line current

Answer / guest

voltage which differs in apoint to point a current wich has
phase supply

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?
