Heat Run - Temperature Rise
Liquid cooled transformers default to stability
check on Oil Top. Dry type transformers default
to stability check on winding and core.
Dry type transformer setup is only for the heating
part of the test. There is no step 2, rated current
injection. It is only necessary to specify the
temperature rise, stable temperature duration
and recording interval.
10.3.3 Temperature Settings
The temperature measuring screen is accessed
by clicking the Setup button, under the
temperature folder in the function key bar.
Activate the used probes by clicking the left side
check box.
Click on the single probes line to enter the
configuration dialog of the single probes (position
& description)
Actual reading of the six temperature channels. To be added
to the medium temperature they should be selected. A
description (text) can be added to every temperature
channel.
By clicking on a sensor line in this list you enter the
temperature probe definition dialog:
Select the position where the sensor is mounted on the DUT
by clicking on the transformer icon.
In the heat run measurements, the standard based
calculations are implemented with respect to specific probe
positions. (see related heat run chapters)
In resistance measurement only the simple mean
temperature of the activated sensors is taken.
Here an additional text for the sensor can be added (e.g.
when an external sensor is used on a cooler fan)
