 The Megger MIT1525/2 is an Advanced 15 kV insulation resistance testers is ideal for engineers and technicians performing insulation testing on transformers, motors, switchgear, and cables in environments up to 230 kV. These instruments support IR, DAR, PI, DD, SV, ramp, and PDC (with software), providing the diagnostic depth needed for condition assessment and maintenance planning.

Each model includes PI Predictor™ to speed up testing, internal memory for storing results, and optional Bluetooth® for exporting data to PowerDB or CertSuite — no manual recording required.

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.

The MIT1525/2 has a 15 kV test voltage. With 6 mA noise immunity and high-performance guard terminals, the Advanced range delivers reliable results where remote control and substation-level noise handling are not required.
