What is the max demand on your transformer and your company?

Answer Posted / mohd. karim

i want to give answer of this que. by an Example:

**if connected load of our system( factory,
Works,plant ...Etc) is 1250KW(1.25MW)...it means our maxi
demand at PF 0.83 is 1506KVA (1.506MVA)

one transformer used for this load with rating PF 0.8,
11kv/0.415, 1500kva
***it means MD in KW is 1200KW
MD in Kva is 1500KVA (1.5MVA)

it means this x-mer is not suitable for this load because
efficiency of x-mer is maxi. at half load. for above
example, this x-mer is suitable for 600KW-850KW at
PF=0.83)
Here
** is the MD of Company
***is the MD of X-mer

Is This Answer Correct ?    25 Yes 5 No
