iTIG II Model B Motor Tester and Analyzer Details

This model is designed for those who want Insulation Resistance (megohm), DC Hipot and Surge tests plus one or more of the following: reporting capability and/or milli Ohm winding resistance measurement.

Like all Electrom iTIG II surge testers and winding analyzers, the Model B is extremely easy to use. For a 3-phase motor the output leads from the iTIG II are connected to the motor’s phases and not moved between the tests. An internal lead switching matrix connects the right leads automatically when a test is chosen on the tester’s touch screen.

Once the operating voltage of the motor is entered, the high frequency surge tests, with fast rising pulses per IEEE 522, can be done automatically. There is no need to further adjust voltage range and sweep (or time base), it is all done by the tester. Quick Surge™ and Surge Guard™ technology find more insulation weaknesses and faults, makes the tests faster, and ensures the right number of surge pulses are applied for optimal performance.

Surge tests of assembled motors can be done without turning the rotor by using the Pulse to Pulse surge tests.

Four-wire milli Ohm Winding Resistance is measured through a six lead Kelvin clamp lead set that plugs into the front panel. For a 3-phase motor, push a button and three the three resistance measurements are done automatically. Both winding resistance and insulation resistance (megohm) measurements can be temperature compensated per IEEE standards.

Polarization Index (PI) and Dielectric Absorption Ratio (DAR) can be calculated by the motor tester.

The instrument can virtually store an unlimited number of test files. Reports can be generated on the motor tester and transferred to a PC saving significant time. Alternatively they can be generated on a PC with the use of the TRPro-B report software, which is included with the tester. It runs on one or multiple PCs and servers, and generates documents for print or email. Options  for network/wireless transfer of test data and reports are also available.

Reports and screens on the motor tester are available in multiple languages.

The B model can be upgraded to a C or fully automatic D model.
