Description
Megger DET2/3 Ground Tester Repair
The Megger DET2/3 Ground Tester is an insulation resistance tester – it generates a high DC test voltage and measures the very small leakage current that results. Those two demands pull in opposite directions, and both have to be verified: producing the voltage, and resolving nanoamps while doing it.
The Megger DET2/3 Ground Tester is repaired at June Company by technicians who work on this class of instrument daily, for electrical contractors, maintenance electricians, motor shops, and cable testing crews. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Megger DET2/3 Ground Tester problems we fix
- Battery or charging faults.
- Test voltage low or not generating – a tester producing a fraction of its nominal voltage still returns a plausible resistance figure that is simply wrong.
- High-range resistance readings inaccurate – drift shows first at the top of the range, where the currents involved are smallest.
- Will not discharge the circuit after test.
- Guard terminal or lead faults.
- Timed test or polarisation index functions failing.
- Readings drifted out of tolerance – corrected and verified against reference standards.
- Display, keypad or front-panel faults.
FAQs
Are the measurements verified after repair? Yes, against reference standards, with the measured results documented and returned with the instrument.
How do I know the test voltage is correct? It cannot be inferred from the resistance reading, so we measure the actual output voltage as well as the measurement circuit.
