Answer Posted / hm
capacitor injects reactive power to the circuit(charging
current leads voltage across capacitor: see from power
triangle). since reactive power unit is KVAR(Kilo Volt
Ampere Reactive) capacitor rating also measured in KVAR

11kv/433v delta/star distribution transformer primary side full load Ht current is 83.33A in , but input side VCB rating 800A.why?
Power factor =1.000 at factory in supply. However, PF = 0.8 at motor end. Current = 100 Amp, Voltage = 400 V. What is the power distribution loss? Can I reduce it by adding capacitor at the load feeder?
how to calculate differential current when we testing differential relay..suppose we have 1000kw generator,630amp VCB,what value we should put /inject so that relay trip the VCB? PLLZ justify ur comment

calculate external resistance values to add to the rotor of a slip ring induction motor. STATOR- 415 V, 3 phase delta, 1100 A, 50 Hz, 1490 rpm, pf 0,86 ROTOR - 660 V, 590 A, 50 Hz. STATOR current at each steps STEP1-600A,STEP2- 800A,STEP3-1000A,STEP4-1100A.
why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?
