  • HTZZ-40A Transformer Resistance Meter

    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...

  • YDQ Power Frequency Withstand Voltage Test Set (Gas type)

    YDQ series are essential equipment during electrical equipment tests and preventive tests. With the development of China's power industry, people required higher about the voltage class of testing transformer, and the traditional oil / dry type test transformer cannot meet the requirement in volume, weight, and functions. With the development of Chinese basic scientific research, the appliance of new material...

  • GM-5KV Adjustable Insulation Resistance Meter

    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 ...

  • HT2671 Digit Megohmmeter

    HT2671 Digit Megohmmeter consists of medium and large scale integrated circuit with high output power and high short-circuit current value features. The output voltage is up to four grades. The built-in battery served as power supply become high DC voltage by DC/DC transformation, which goes from E pole to L pole via the object being tested. By this way, it produces a current from pole E to pole L, which converte...
