To be fully in conformance with the most modern testing requirements, Megger offers a family of the highest quality insulation testers at voltages above 1 kV. At the core of high-voltage testing, the 5-kV models, MIT510/2 and MIT520/2, afford the highest level of quality testing along with prime safety, convenience and portability. The testers measure to 15 Tera-ohms, thereby making them fully suitable for critical installation tests and establishment of reliable base data for new high-capital equipment.

MIT510/2 offers selectable test voltages at 250, 500, 1000, 2500, and 5000 V, making the tester suitable for applications otherwise performed with a standard handheld model, in addition to the more demanding high-voltage applications. The MIT520/2 increases the functionality by permitting test voltage to be set in any 10 V increment from 50 V to 1 kV, then in 25 V steps all the way to 5 kV.

For complete insulation testing capability of all high-capital equipment, Megger offers a 10-kV unit. The universal testing standard for rotational equipment, IEEE 43-2000, increased the test voltage recommendation to 10 kV for equipment rated 12 kV and above. Full compliance with this standard can be attained with the MIT1020/2. This model offers all the capabilities already mentioned, plus an increased test voltage to 10 kV. As with the MIT520/2, test voltage can be set in 25 V increments, but now all the way to 10 kV. Measurement range has been expanded commensurately with the highest rated equipment, to 35 T.
