station supplies 250KVA at a 0.8 power factor lagging.A synchronous motor is connected in parallel with rhe load.if the combined load is 240KW with a lagging power of 0.9calculate the leading KVAr by the motor

a 6.6kv, y-connected, 3phase alternator has a synchronous reactance of 6 per phase and a negligible resistance. at a certain field current the armature is known to induce 5.8kv per phase. calculate the max power that can be developed by the alternator at this excitation

2.) A businessman is faced with the prospect of fluctuating future budget for the maintenance of the generator. During the first 5 years, P1,000 per year will be budgeted. During the second five years, the annual budget will be P1,500 per year. In addition, P3,500 will be budgeted for an overhaul of the machine at the end of the fourth year and another P3,500 for an overhaul at the end of 8th year. Assuming compound interest at 6% per annum, what is the equivalent annual cost of maintenance?

Ans. P1,888.87
