Answer / power team

* Power Consumption is less in case of Three Phase Circuit
(P= sqrt of 3 * Vph * Iph * PF)where as in single phase
circuit,power consumption is more(P= Vp * Ip *PF)

* Efficiency is much better in 3Ph circuit than 1Ph circuit

* Cost of transmission is high in 3Ph circuit

* Voltage regulation is better in 1Ph

* 3Ph circuits are widely used by Industrial HT consumers
