  • HTZZ-50A Transformer DC Resistance Tester

    DC resistance measurement of transformer winding is an essential test project during transformer delivery, repair and changing tapping switch. Usually, it is a time consuming task to use traditional methods (bridge method and voltage drop method) to measure transformer winding and DC resistance of high-power inductive device. In order to change this situation: shorten measurement time and reduce the staff’s w...

  • HTHL-100A Micro Ohmmeter

    Nowadays Power Systems widely use model QJ44 DC double arm bridge to measure contact resistance (DC resistance and Loop resistance of high-voltage circuit breaker) while the minimum current of such model is 1mA which hardly find the decrease of cross-sectional area of transformers’ conductive circuit conductor. The measurement of loop resistance of high voltage switchgear is affected by oil layer and oxide betwee...

  • GM-10KV HV Digital Megohmmeter

    For safety, before use the instrument must be well earthed. That’s because the measured target connects to high voltage power, and exists power frequency leakage.  Once high voltage has started, do not use manual discharge method to check the instrument. After test, please wait the instrument completes automatic discharge and automatically returns to zero, then manual discharge can be operated. That is b...
