The voltage difference between 2phases is called phase
voltage.line voltage is flowing of voltage in that
line

Line current is defind as maximum amount of current
flowing in that
line.
phase current is defind as the current diffrence
between to phases

We have a 12MW power plant & we inject 5-6MW power to Orissa GRID. For this we have a 33KV/11KV switch yard having 12.5MVA power transformer. Some times we draw power during emergency. It is observed that during Export or Import for load less than 500Kw the power factor is decreasing to 0.3 . This is happening only during export or import. During island condition TG power factor OK.Our capacitor bank is provided with our Power plant auxilliary load. Please suggest how I can we improve our power factor during low load (GRID).
