A 66.7 MVA transformer has an efficiency of 99.3 percent when it delivers full power to a load with a power factor of 100 percent.

Calculate the losses in the transformer under these conditions.

Answer :

To calculate the losses in a 66.7 MVA transformer with 99.3 percent efficiency, the percentage loss is found by subtracting the efficiency from 100 percent, and the result is multiplied by the power rating of the transformer, which gives the losses as 467 kW.

The question asks to calculate the losses in a transformer that has an efficiency of 99.3 percent when delivering 66.7 MVA of power at a power factor of 100 percent. The efficiency of a transformer is calculated as the ratio of the output power to the input power, expressed as a percentage. To find the losses, one must subtract the transformer's efficiency from 100 percent and multiply the result by the transformer's full power rating.

First, calculate the loss in percentage:

100% - 99.3% = 0.7%

Then, convert this percentage into absolute losses by multiplying by the full power rating of the transformer:

0.7% imes 66.7 MVA = 0.467 MVA or 467 kW (since 1 MVA = 1000 kW)

Therefore, the transformer losses are 467 kW under these conditions.
