In power plants the reading changes abruptly to give value
(MW -25) (MVAR -15)
What are the reasons for this?
What is the solution?
Answer Posted / sonu pal
MW is active power and MVAR is reactive power.
Active power, P= V.I.cosΦ
Reactive Power, Q= V.I.sinΦ

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.
