  • Description

    Metrel MI3205 TeraOhmXA 5kV Insulation Tester

    The Metrel MI3205 TeraOhmXA 5kV Insulation Tester is a piece of industrial equipment that is suitable for testing transformers, transducers, high voltage generators, production lines, varistors and surge arrestors. It is also suited to testing insulation on rotating machinery and cables.

    The Metrel MI3205 has test voltages from 50V to 4.99kV in 50V and 100V steps which allows it to measure insulation resistance between 0.01MΩ and 15TΩ with a maximum resolution of 10kΩ and a best accuracy of ±(5% + 3 digits). Test voltages can be applied in a step voltage test – ideal for testing varistors – and the tester also has a programmable timer.

    Diagnostic functions for insulation testing include dielectric absorption ratio, polarisation index, and dielectric discharge (all from 0.01 to 100.0). The Metrel MI3205 has an additional high voltage breakdown detection feature as well as a guard terminal and automatic discharge of target objects following the tests. The user can set their own automatic test sequences and tester has automatic adjustment for the specific requirements of a test.

    Other measurements are possible with the Metrel MI3205 including insulation leakage current from 0.00nA to 5.00mA, capacitance from 20nF to 50µF, voltage from 5V to 550V, and finally frequency from 10Hz to 500Hz. High frequency input AC current noise rejection and additional result averaging helps negate the effects of interference.

    Numerical and graphical results can be shown on the Metrel MI3205’s vibrant colour screen and it can save results to its internal memory. Operation is conducted using the simple navigation buttons and intuitive interface whilst USB, RS-232 and wireless Bluetooth connections are available for data transfer. The supplied Metrel HVLink PRO software package facilitates downloading, analysis and reporting.

    The Metrel MI3205 is capable of working from the mains or from its own rechargeable battery and has an overvoltage rating of Cat IV 600V. It is suitable for use in challenging industrial environments thanks to a robust design that boasts an IP54 ingress protection rating when open and an IP65 ingress protection rating when closed.

    Supplied accessories include shielded test lead, a guard lead, crocodile clips, a calibration certificate, a USB cable and an RS-232 cable.
