£2,750.00
The Megger MIT515 is a professional 5kV insulation resistance tester for fast, dependable testing on transformers, motors, cables, and switchgear. It performs core IR tests including timed IR, PI, and DAR, with resistance measurement up to 10 TΩ at 5kV. The MIT515 focuses on productivity with rapid charge batteries and the ability to operate from AC power if the batteries are depleted. It is safety rated to CAT IV for field use and includes live circuit detection to help protect users.
Megger MIT515 5kV Insulation Tester
Megger’s 5kV DC insulation testers set the industry standard for insulation resistance testing. Designed for diagnostic testing and maintenance of high-voltage electrical equipment, these rugged, portable instruments offer unparalleled performance, safety and reliability for OEMs, industrial companies, electrical contractors and utility providers. Select test voltages from 250V up to 5kV and run IR, PI, and DAR for condition assessment. Timed IR simplifies repeatable test routines, while automatic discharge and clear on-screen guidance keep operation straightforward on site. Designed for industrial environments, the MIT515 can be powered while charging so work does not stop mid-task.

Megger MIT515 5kV FAQs
What is the difference between MIT515 and MIT525.
Both are 5 kV instruments. The MIT515 provides IR, PI, and DAR but has no on-board memory. The MIT525 adds diagnostic tests such as step voltage and dielectric discharge, plus memory and download.
Can I select intermediate test voltages.
Yes. Five presets are available and voltages are user selectable in fine steps to tailor tests to your asset and procedure.
What is the maximum insulation resistance the MIT515 can measure.
Up to 10 TΩ at 5 kV.
Can the unit run while charging.
Yes. The range supports measurement when connected to an AC source if the battery is discharged.
Is this suitable for site use.
Yes. It carries a CAT IV 600V rating and includes live circuit detection to help prevent testing on energised systems.
