Answer / pundlik m wanwe
As the winding is the source of heat generation and the oil
is meant for cooling the same. winding temperature will be
always greater than oil temp.

Answer / rithesh
well dts true...total load will be on the winding and the
source generates heat....dts the reason the winding temp is
higher than the oil temp
| Is This Answer Correct ? | 8 Yes | 2 No |
Answer / k.shivkumar
Normaly winding temperature is higher than oil temperature
because Oli is cooling medium and delta T should be 6 to 10
Degree celcius

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill. Q: Identify the appropriate solution you want to offer to Client?.Justify SCIENTIFICALLY and MATHEMATICALLY the principles behind the solution.
