The function of magnetic assistant matrix and option matrix is added to JYR 40E Transformer heat run winding resistance tester on the base of JYR DC Resistance Tester (20D)、(40D,), the wiring is simplified, the magnetic assistant and option items can be finished by one time of wiring. The demagnetization function is added, and the residual magnetism of the transformer after contentment is reduced. The DC resistance measuring range is extended from the original 0~130Ω to 0~40kΩ. The instrument also can measure the resistance of the transformers and instrument transformer with high resistance, to realize one instrument with multiple usages.




Function Introduction

● JYR 40E Transformer heat run winding resistance tester is suitable for DC resistance test and heat run test of 240MVA and below transformers.

● With the third constant current source technology, the measuring rang is from 0 to 40 kΩ.

● Operated by touching the colorful screen, the operation is more simple.

● The two channels can be tested simultaneously.

● JYR 40E Transformer heat run winding resistance tester with function of magnetic assistant matrix and option matrix

● the function of residual magnetism.

● accuracy is improved, the minimum resolution can reach 0.01 µΩ.

● The interval time during the temperature rise test is 10s, 30s and 60s for option.

● print timing.
