What is meant by Active and reactive power?

Answer Posted / r.r.pandian

Active Power:Which is convert from electrical energy.it is
measure by W,KW,MW
Reactive power:It happens in circuit at the time of current
flowing and induced magnetising.It is measured by Kvar.
Apparent Power:It is not converted,It is transforms
electrical energy.(Voltage depends cu loss,current depends
Iron loss)It is measured by VA.

These are Three types of power.

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.
