This function can be used to correct
temperature losses on the thermometer
pocket.
The default setting is „temperature correction“ off
<Temp-Cor.OFF>.
When <Temp-Cor.ON> is activated, a correction value is set
internally which was determined from studies of temperature
measuring devices and sensors on transformers. The
temperature loss due to the thermometer pocket begins at an
oil temperature of approx. 30 °C and increases as the oil
temperature rises.

This menu item can be used to indicate

the actually fed in CT current multiplied
by the CT current ratio.

The load factor K specifies the ratio
between load current and rated current.
If the rated current is 1000 A and the
actual load current is 500 A, the load
factor is 0.5 (the load of the transformer
is 50%).
