how a synchronous motor is used as a resistor,capacitor and
an inductor?
Answer Posted / ilayaprabha
when the synchronous motor is run in normal condition , it will act as a inductor. it draws the lagging current from the supply.
when the synchronous motor is run under over excitation, it will act as capacitor that means it draws the leading current from the supply.
this is the key to improve the power factor.

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.
