Transformer Test Report Missing data for PTLoad Heatruns
Transformer Test Report Missing data for PTLoad Heatruns
(OP)
I'm currently doing heatruns using EPRI's PTLoad to find the maximum overload a transformer can take.
Under old standards the temperature rise was 55 degree celsius but now it is 65 degrees.
The transformers I'm doing the heatruns to are very old (mfg. before 1970), and therefore have test reports with 55 degree rise data.
I need to find a way to use the data of this old test reports to do heatruns and obtain results according to the the 65 degree temp. rise.

I'm sure we will get some more input.

I can't recall if it addresses the older temp rise standards, but there might be enough of what you need to create your own s/w.
Alternatively, the earlier standards , such as the 1962 version of ANSI C57.92 and NEMA TR98-64 have tables that guide you for loading capability. I am assuming your tx/s are designed to those older specs, of course.
Hope this helps,
