Answer / thankappan

when your connected the indective load ( e.g.motor, which
was get a megnetic field. )in the power circuit, power
factor going to Lagging. So, need Increased the power
factor to leading in the power circuits, parralled
connected the capcitor in the power circuits. so, voltage
also increased, load current reduced.
