    Megger Insulation Tester Details

    Tips: Main function of insulation resistance tester

    1. Repair the defective parts

    Technicians use the Megger to verify the high insulation resistance between conductors and ground or between adjacent wires. By testing the insulation resistance of different components of the system (transformers, switching devices, wires, motors), the technician can isolate and repair the parts that have failed.

    2. Improve system performance

    Before powering the system, use the insulation tester to verify that the system is sound and can improve the performance of the system.

    3. Found manufacturing process problems and equipment defects

    Insulation testing can be used to detect manufacturing process problems and equipment defects that are generally not detected before equipment failure. In the European Union, the insulation test is mandatory, even for the smallest civilian systems.

    Perfect megger insulation tester for my job
    I need a 1000v megohmmeter to test cable insulation. Since receiving this product, I have retired my old multimeter. I did a lot of research before buying because I needed the tool to do my job and yes, this resistance tester really did.

    High quality megger insulation tester
    Hi, loking for your cable insulation tester to be used in a automated go- no go test set-up. Is the ATO-IRT UT512 full controlable over the USB port? If yes, is there testsoftware set-up available?

    ATO Responded
    Our insulation tester ATO-IRT UT512 will be shipped to you with USB port and test software set-up is available, but the software is just to view the measurement data in real time & save historical data only, but it cannot automatically do/complete measurement.
