Line to Line voltage or Phase to phase voltage is the
common way of representing the voltage. Also called as Line
voltage in Electrical System.

In case of 3 Phase system the Phase voltage (Line to
Neutral Voltage) is {{LINE VOLTAGE/ Root 3}} Therefore the
Single phase voltage is 400/1.732 That is near 230Volts.

why induction motor having low power factor at starting time and high at full load.

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill. Q: Identify the appropriate solution you want to offer to Client?.Justify SCIENTIFICALLY and MATHEMATICALLY the principles behind the solution.
