Transformer Tertiary is not loaded, why its winding temperature higher
Transformer Tertiary is not loaded, why its winding temperature higher
(OP)
THe tertiary is not connected to the load, but its winding temperature gauge reading is highest among the three windings.
I would like to listen to your opinion.

My question was, if there is the zero load current in the tertiary (tertiary is not connected to the load), how the tertiary winding temperature was higher than the other two winding? the winding temperature of tertiary should not exceed the oild temperature.

If it is broken, fix it. If it isn't broken, I'll soon fix that.

Is the CT feeding the gauge on the tertiary bushings, or on the delta part of the winding? If they are on the bushings you have a calibration problem.
Are they separate gauges or an electronic monitor?
