Three Gorger Project is attracting worldwide attention, mono block transformer capacities reaches 840 MVA, create the best in China, it was made together by Siemens Germany, Baoding Tianwei and Shenyang transformer factory. 80100 transformer direct-current electric resistance testing instrument have been to develop specially to resolve the difficult problem that temperature-rising tests have been suitable to the request that 220kV and the transformer above 220kV temperature test, have passed the strict acceptance check, having reached advanced world level, have filled in the blank in China.

FUNCTION INTRODUCTION
●.Adapt to the temperature rise and winding resistance testing for above 240MVA large-scale transformers.
●The testing data is stable and accurate within 2 minutes as measuring 840 MVA transformer low voltage winding resistance.
●Unique double channels design can demonstrate the measured data synchronously.
●Testing data automatically print per 60 seconds

●Match the conversion software of temperature rise, the value of temperature rise can handle automatically.
