If you are a transformer manufacturer or transformer service company, you may often encounter such problems during the DC winding resistance test of transformers. The winding resistance tester is heavy and inconvenient to carry, and can only be limited to certain areas by the length of the power line. If the power line was too long, it will be affected by electromagnetic interference.
Kingrun has developed a brand-new handheld transformer DC winding resistance tester JYR-9310 for transformer manufacturers and customers subject to power supply restrictions. This instrument is handheld, wide test range, has temperature conversion function, copper/aluminum selection, accurate reading, one-time charging measurement of hundreds of transformers, etc.
