1 4268how we calculate electricity unit ( meter unit.. for knowing how many charges) from on motor load.?
2 3179A 10 MVA, 66KV, 50Hz, Y-connected 3-phase alternator has synchronous reactance of 0.635 Ù. It is working at full load at 0.8 lagging p.f. condition. Find torque angle, neglect armature resistance.
VECL,
2593With a phasor diagram show the effect of increasing the field current of a generator supplying a constant real power and connected to a grid system.
VECL,
1976Draw the wave shape of armature current in a generator subjected to a sudden three phase short- circuit at its terminals. Define various reactance of generator from this wave shape.
VECL,
2225A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.
VECL,
1920A generating system will have a total capacity of 300 MW. Find the probable forced outage when the capacity is supplied by two 150 MW units. The operating probability of all units is P=0.98 and forced outage probability rate Q =0.02 .
