Much like a leak in a water pipe, an imperfection in the insulation of a wire allows a steady flow of electricity to escape, which can be detrimental to electrical circuits and machinery. However, testing can help you determine if the insulation is performing at an effective and safe level. Routine testing with the Megger MIT1025 10-kV Insulation Resistance Tester 10-kV Insulation Resistance Tester can identify problems before they result in injury or equipment failure.
The Megger MIT1025 10-kV Insulation Resistance Tester insulation resistance tester measures insulation resistance, voltage, current, and capacitance in high-voltage electrical systems.
A multiranging digital meter that performs timed insulation resistance (IR), polarization index (PI), dielectric absorption ratio (DAR), dielectric discharge test (DD), step-voltage (SV), and ramp tests, the MIT1025 measures insulation resistance from 10 kilohms to 20 teraohms, voltage from 30 to 660V alternating current (AC) or direct current (DC), current from 0.01nA to 6mA, and capacitance from 10 nanofarads to 25 microfarads.
The MIT1025 has test voltages in 10V steps from 100V to 2,500V and in 25V steps from 2,500 to 10,000V. It also has 250, 500, 1,000, 2,500, 5,000, and 10,000V set test voltages.
