    15kV Insulation Resistance Meter - Overview

    The MIC-15k1 meter is designed to measure the insulation resistance of power objects up to 15kV, i.e. single and multicore cables, transformers, motors and generators, capacitors, switches, and other devices installed in power stations. It is especially recommended for measurements in areas with very high electromagnetic disturbances, e.g. electrical substations with 1200 kV AC and 500 kV DC. Thanks to the 15 kV measuring voltage (in accordance with ANSI / NETA ATS-2009 TABLES 100.1) the meter can be used for measuring objects with a nominal voltage above 34.5 kV.

    15kV Insulation Resistance Meter - Features

    • Diagnostics of insulation systems based on standard measurements of IR, DAR, PI, SV, RT, and DD, widened with the partial discharge (PD) indicator for each of these measurements
    • Testing the electrical durability of tested object - breakdown voltage indication
    • High resistance to electromagnetic interferences - uninterrupted work in power stations & close to high voltage transmission lines up to 1200 kV AC & 500 kV DC
    • Smooth voltage rise in time function (RT - Ramp Test) - state the partial discharges in the facility and carry out a partial location of their occurrence
    • Efficient converter with a power of ~150 W enables insulation burnout, allowing for pinpointing the location of cables and wires short circuit using one of the following:
      • visual method (if power cables are visible along the entire length)
      • reflectometric methods, seismic-acoustic waves detector, or with A-frame to indicate the direction of the fault (the conductor must be buried in the ground with earth direct contact)
    • Compatible with external software
