what are load calculations for a transformer???

shaibaaz3

A 44kv line is distributed into the industry using around 8 transformers 3750kva, 2500kva and 1500kva. What does this mean and what are the load calculations for this???? Also how is it distributed???

KVA is simply volts times amps. And, it's usually three-phase, so you divide the line-to-line voltage by the square root of 3 to find the line-neutral voltage. So, for example, if you have 44 kV into a 3750 kVA transformer, the maximum current will be 3750 / (44 / SQRT (3)) / 3 = 49.2 amps per phase primary current.

thank u.....

Distribution of load on individual transformers is related to their rated power and impedance voltage. For detail calculation you can refer to Transformer Riddle No. 27 from http://electrical-riddles.com
