Perform essential insulation tests quickly and accurately on motors, transformers, cables and other electrical assets.
Stable, accurate results:
- 3 mA noise immunity supports consistent performance in typical industrial or distribution-level sites up to 45 kV.
PI Predictor™ cuts test time in half:
- PI Predictor™ estimates PI values in minutes, improving productivity with no loss in accuracy. Ideal for multiple asset tests.
Accurate testing with Re<Act™:
- Re<Act™ shows when insulation is ready to retest, avoiding errors from residual reabsorption current. Save time between tests, and safely monitor discharge to avoid dangerous return voltages.
Designed for real-world use:
- Robust casing and IP65 protection (lid closed) withstand knocks, dust, and tough environmental conditions.
Operator safety built-in:
- CAT IV 600 V rated, with live circuit detection and locking terminals to protect users in active environments.
The range includes two models: the MIT515 (up to 5 kV) and MIT1015 (up to 10 kV), both supporting insulation resistance, dielectric absorption ratio (DAR), and polarisation index (PI) testing. Megger’s PI Predictor™ reduces PI test duration by up to 50%, boosting productivity when testing multiple phases.
The new innovative patent applied Re>Act test mode allows the user to make accurate measurements by monitoring reabsorption current. This groundbreaking test mode can ensure reabsorption current does not result in incorrectly passing or failing insulation, helping to maintain safety. In addition, the test mode can be used to ensure dangerous return voltages to not occur.
These instruments have no onboard storage and a fixed 3 mA burn/charge current—perfect for environments where advanced features like remote control aren’t required. The high-performance guard terminal ensures measurement accuracy even in high-leakage conditions.
Simple to use, CAT IV 600 V rated, and built for demanding industrial, OEM, and utility applications, the Essential range delivers fast, dependable results—without complexity.
