The Megger MIT1025/2 is a 10 kV insulation resistance tester engineered for high-voltage electrical testing in demanding industrial and power distribution settings. Part of the Advanced series, this instrument provides engineers and technicians with the reliability and precision required for comprehensive diagnostics on assets like cables, transformers, circuit breakers, and motors. Its dual-case construction ensures rugged durability, offering an IP65 rating for protection against moisture and dust when closed.

This tester excels in electrically noisy environments, featuring up to 6 mA of noise rejection to deliver stable and accurate measurements. The MIT1025/2 is equipped with a full suite of diagnostic tests, including Polarisation Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Stepped Voltage (SV), and Ramp testing. For enhanced efficiency, the patented PI Predictor function provides an estimated PI value in as little as three minutes, significantly reducing test time on-site.

Safety is a core design principle, with a CAT IV 600 V rating up to 3000 m providing a high level of user protection. The instrument also features multiple voltage warnings and locking test leads to prevent accidental disconnection. Test voltages are user-definable from 100 V up to 10 kV, offering the flexibility needed for various applications.

Data handling is streamlined through on-board memory that logs time and date-stamped results. Data can be transferred safely via an isolated USB port or wirelessly with Bluetooth LE, allowing for seamless integration with CertSuite Asset and PowerDB software for creating reports and analysing trends. The fast-charging Li-ion battery provides up to 4.5 hours of continuous testing at 10 kV and can be operated from an AC power source for uninterrupted use, making the MIT1025/2 a dependable tool for predictive maintenance and quality assurance.

Frequently Asked Questions (FAQ)

1. What makes the Megger MIT1025/2 suitable for high-voltage environments?
The MIT1025/2 is designed with a maximum test voltage of 10 kV and a CAT IV 600 V safety rating. It also features high noise immunity and is supplied with test leads specifically insulated for 10 kV use, making it ideal for testing high-voltage electrical systems.

2. Can I use the MIT1025/2 if the battery is depleted?
Yes. The instrument can be operated directly from an AC mains supply, allowing you to continue testing without interruption even if the battery is fully discharged.

3. How does the MIT1025/2 simplify data logging and reporting?
It features on-board memory for storing time-stamped test results. You can easily transfer this data to a PC or mobile device using the isolated USB or wireless Bluetooth LE connection for use with Megger’s CertSuite Asset or PowerDB software, streamlining analysis and report generation.

4. What is the benefit of the PI Predictor function?
The PI Predictor is a time-saving feature that uses the initial part of an insulation resistance curve to predict the final Polarisation Index value. This can provide a reliable result in as little as three minutes, compared to the standard ten-minute test, improving on-site productivity.

5. What is included with the Megger MIT1025/2?
The MIT1025/2 is supplied with a power lead, a screened USB cable, and two sets of 3m test leads: one set with medium-sized clips and another with large clips insulated for 10 kV use.
