    RD9914B Insulation Withstand Voltage Tester

    RD9914B insulation withstand voltage tester is a safe and high-performance tester designed with high-speed MCUs and large-scale digital circuits.. The voltage rise and fall as well as the voltage frequency of the instrument are controlled by the MCU. It displays the breakdown current and voltage values in real time. And it’s also with the software calibration. Equipped with PLC, RS232C, USB interfaces, it is convenient to form a comprehensive test system with computer or PLC system. It can intuitively, accurately and quickly test the electrical safety performance indicators such as breakdown voltage, leakage current, insulation resistance and other electrical safety indicators of various measured objects.

    Purpose and test method of AC withstand voltage test for transformer

    The AC withstand voltage test is a destructive test in the insulation test. It can only be carried out after other non-destructive tests (such as insulation resistance and absorption ratio test, DC leakage test, dielectric loss tangent and insulation oil test) are passed. After this test is passed, the transformer can be put into operation.
