Answer Posted / shiva prasad
P= POWER
P= V X I X COS@ IN AC
KW = P X 1000
KW= KILO WATT
KVA= IT IS NOTHING BUT KW
KVAR= V X I X SIN@ IN AC
KW= KVA X PF

what is the ms flat constant for calculating earth mat design calculation?
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.
