HEAT RUN TEST SOFTWARE
The Heat Run Test Software, option 2042N-11001, is used to analyze the measurement results of the
copper loss test of the windings of a transformer and to calculate the resistance values of the winding at
the working temperature (time zero).
INTRODUCTION
The Heat Run Test (HRT) performs a measurement during the cooling curve of a transformer after the
transformer has been heated.
The measurement is made in the interval
15
mode without temperature correction.
In the Setup Menu the following settings must be made:
Activate “Interval Mode“ and select the interval time.
Select the time in seconds between measuring
points (Interval Time) and the number of data points
