Answer Posted / ibrahim
We generate reactive power (within a limit) with help of
changing excitation
for example .8 pf alternator is possible to operate at unity
by changing excitation .8 is the limit to generate reactive
power.if below .8 then we reduce real power only to generate
more reactive power.
But in motor full load it operates at .8 p.f only.......

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 ?
