what is reactive power
is it good or bad for a system
Answer Posted / n.krishnaswamy
When power factor decreases more power is drawn and energy charges will increase.So power factor is to maintained near to unity.In our state,for an HT consumer, if power factor is less than 0.9 there will be exorbitant fine.I f it is maintained above 0.95,we will get good incentive.In one of my project, the total energy cost is Rs.17 lakhs. Since the power factor is maintained 0.99, the incentive is Rs.83000/-

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
is the value of inductance depends upon the value of thitha in doubly excited machine??
