Answer / adnan

Power factor is cos of angle between voltage and current. Leading and laagging of pf means, if current is leading voltage or behind voltage.
To understand leading and lagging of voltage and current refer to sinusoidal graph of voltage and current.
PF can never be more than 1, as value of cos (phi) never exceeds 1.

6.6 KV /.415KV Step down trf. we can get 6.6 KV from primary by applying .415 KV secondary side by same TRF.
