Megger MIT1020.2 10kV

The Megger MIT1020.2 10kV Insulation Resistance Tester is a rugged, high-performance diagnostic instrument designed to accurately measure insulation resistance in medium‑ and high‑voltage electrical systems. Delivering stable DC test voltages up to 10 kV, this tester is ideal for evaluating the insulation condition of power cables, transformers, switchgear, motors, generators, and other critical electrical assets.

Built for field use in utility, industrial, and commercial environments, the MIT1020.2 combines precise measurement technology with a robust, portable design that withstands demanding conditions. With a wide measurement range extending from megohms (MΩ) into the teraohms (TΩ) range, it enables technicians and engineers to detect early signs of insulation degradation, contamination, moisture ingress, aging, and potential faults before they lead to failure.

The MIT1020.2 supports a comprehensive set of test functions tailored for thorough insulation analysis, including:

Insulation Resistance (IR) Testing at selectable DC voltages up to 10 kV

Polarization Index (PI) for evaluating long‑term insulation performance

Dielectric Absorption Ratio (DAR) for deeper insulation condition assessment

Step Voltage Testing to examine insulation behavior under increasing stress

Leakage Current Measurement for pinpointing insulation flaws

Automatic Discharge of the test object after completion, enhancing safety

Safety and ease‑of‑use are core elements of its design. The instrument features clear visual displays for real‑time readouts of test voltage, resistance, and leakage current, along with intuitive controls for quick test setup. Integrated safety protections — such as zero‑start interlocks, voltage‑presence indicators, discharge circuits, and rugged enclosure design — ensure secure high‑voltage operation even in challenging field settings.

To support asset management and maintenance documentation, the MIT1020.2 offers internal data storage and PC connectivity for exporting results and generating professional reports. This capability makes it a valuable tool for condition‑based maintenance, compliance verification, and preventive maintenance programs.

Whether performing insulation tests on underground power cables or validating transformer insulation integrity, the Megger MIT1020.2 provides reliable performance, accurate measurements, and essential safety features that professionals depend on to maintain electrical system reliability and reduce downtime.
