the relationship between phase and line voltages in a 3
phase generator is expressed in what formula?
Answer Posted / madasamy
Phase volt is phase to neutral voltage. line voltage is phase to phase voltage
ph.volt = line volt/sqrt(3)
always ph. voltage < line volt

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
What will be the impact on motor performance if a LT motor is rewound with changed motor winding data as given below:- Original winding data: total 04 wires = 02 wires of 17 SWG + 02 wires of 16.5 SWG. Changed Winding data: total 03 wires of 15.5 SWG wire size Motor rating: 160KW, 740RPM, 415V, ID FAN application. Normal Running Current = 95% of FL Current.
