If we have 15000kw connected load in a factory than how much power demand sanction should be taken..

Answer / ashish negi

the above calculation is correct but if we have to give our
demanded load to electricity dept. than the load should be
greater than the load as on starting motors , motors take 2-
3 times the full load cureent and at that time your MDI
(maximum demand index)will go beyond the calculated load.
so in that case your have to pay the penalty. so your
demanded load should be between 2500-3000 KVA.

If we have 15000kw connected load in a factory than how much power demand sanction should be taken..

Answer / rakesh maharjan

Remember the formula
KW=1.732 x V xI x PF
or
KW= KVA x PF, where PF = 0.8
connected load KW= Full load kw x 80%
Here in your case, connected load KW= 15000kw
so full load KW= 15000/80%=18750 KW
KVA= KW/.8
KVA=18750/.8=23437 KVA, this is the demand sanction.

Answer / k.prakashchandra

Only the connected is mentioned and not the peak load.
Maximum demand is registered only if that apparent load
lingers for more than 15 to 30 minutes (as set).You have to
consider load factor(?) also .Apply for 12000 KVA MD
initially and you can apply for higher ,later.Once you get
the MD sanctioned, you can not get it reduced during the
agreement period.
