Htzz-S20A Winding Resistance Meter DC Resistance Tester

Brief introduction
This 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 measuringtransformer DC resistance.
Products featuresCan test the DC resistance YN three phase winding at the same time, shorten the measuring time.Can finish the transformer winding current in short time.With perfect protection function.Small volume, easy to carry.LCD display, easy to read and operate.With fast speed, high accuracy, good reproducibility, strong anti-interference.Product parametersMeasurement Single phase (two phase)Three phaseCurrent gear1A5A10A20A40A1A5A10A20AMeasurement range10mΩ~20Ω1mΩ~4Ω1mΩ~2Ω1mΩ~1Ω1mΩ~0.5Ω10mΩ~6Ω/phase1mΩ~1Ω/phase1mΩ~0.6Ω/phase1mΩ~0.3Ω/phaseMax resolution0.1μΩAccuracy ±0.2%+2d (full range)Data storage capacity150 groups Power AC 220V±22V,50Hz±2 HzService condition Temperature: 0ºC~40ºChumidity: ≤80%RH
