MIT510, MIT520 and MIT1020

5-kV and 10-kV Insulation Resistance Testers

Line supply or battery operated

Digital/analog backlit display

Measurement range to 15 TΩ (MIT510 and MIT520) and 35 TΩ (MIT1020)

Automatic insulation resistance tests

Automatic dielectric absorption ratio, polarization index, step voltage, and dielectric discharge tests (MIT520 and MIT1020)

RS232 or USB download of results (MIT520 and MIT1020)

Ingress protection to IP65

3 mA short circuit current

All three instruments test the insulation resistance of:

High-voltage power cables and high-voltage buses

Large motor/generator windings

Line and substation transformers

They all perform spot tests, step-voltage tests, and dielectric absorption tests for the

following applications:

Acceptance testing at installation to check conformance to specifications.

Routine preventive/predictive maintenance testing after installation.

Quality assurance testing as part of the manufacturing process.

Diagnostic testing to isolate faulty components for repair.

With its higher voltage testing capability, the MIT1020 is the perfect every day work

tool for manufactures, users and maintainers of rotating machinery. Designed in

accordance with the requirements of IEEE43:2000 the MIT1020 is ideal for measuring

the insulation resistance of armature and field windings in rotating machines rated

1hp (750 W) or greater. The standard applies to synchronous, induction and dc machines

as well as synchronous condensers.
