Product Name: Three-Phase Windings Transformer DC Resistance Tester Model NO.: HNZZ-S10A Power Source: AC220V Control: Computer Control Display: Digital Loading Method: Dynamic Load Load Way: Electronic Load Type: Universal Testing Machine Test Current: 1A, 5A, 10A, 20A Data Storage: 150 Groups Max Resolution: 0.1?? Accuracy: Plus and Minus 0.2% Trademark: Huaneng Transport Package: Wooden Box Specification: 440*205*455mm3 Origin: Wuhan China Product Description HNZZ-S10A Three-Phase Windings Transformer DC Resistance TesterIntroductionThis tester is the newest product for transformer DC resistance test; it can test the resistance of the three-phase windings at the same time. When test adjustable loading transformer, do not need discharge, regulate the tap changer directly, testing time is 1/3 of the traditional equipment, shorten the testing time and reduce the labor intensity greatly. Use LCD, easy to read and operate. Equipped with panel type printer and high capacity nonvolatile storage, convenient to save and print test results. Test data is stable, fast, good reproducibility, and is the best choice for field measuring transformer DC resistance.ParameterMeasurement Single phase (two phase)Three phaseCurrent gear1A5A10A20A1A5A10AMeasurement range10mΩ~20Ω1mΩ~4Ω1mΩ~2Ω1mΩ~1Ω10mΩ~6Ω/phase1mΩ~1Ω/phase1mΩ~0.6Ω/phaseMax resolution0.1μΩAccuracy ±0.2%+2d (full range)Data storage capacity150 groups Power AC 220V±22V,50Hz±2 HzService condition Temperature: 0ºC~40ºC humidity: ≤80%RHDimension 440*205*455mm3Weight 17kgFeatures1.Can test the DC resistance YN three phase winding at the same time, shorten the measuring time. 2.Can finish the transformer winding current in short time. 3.With perfect protection function. 4.Small volume, easy to carry. 5.LCD display, easy to read and operate. 6.With fast speed, high accuracy, good reproducibility, strong anti-interference
