### Resolved Question:

8. An oil-filled transformer has a c.m.r. of 500 kVA which allows it to run
continuously in an ambient of 35Â°C with an oil temperature rise of
50Â°C. The transformer has a time constant of 1.5. hours and the ratio of
copper losses to iron losses at c.m.r. is 1.5:1.
After switch-on, the transformer supplies a load of 600 kVA for one
hour and the load then rises to 750 kVA. Calculate the period of time
that the transformer can supply this load without exceeding its rated
maximum temperature. Sketch the heating curves for the two loads.
