Answer Posted / javad ahamad
rms value is expressed in terms of dc. suppose we have a
simple resistive ckt. first we connected a dc source and
applied a certian voltage then noticed the heat produced
in the resistor.then we replae the source by ac and we
adjusted the souce to such a value that it produce the
same heating affect when the dc is applied.that value is
called rms value of ac.
rms value is less than peak vale.

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.
