Home » Products » Meatest M191 Insulation Tester Calibrator
The Meatest M191 insulation tester calibrator is designed for the calibration of isolation testers, megaohmmeters and Hipot testers. The M191 calibrator is based on a programmable high resistance decadence with a range of 10 kOhm to 1 TΩ. The decade is designed for voltages up to 10 kV. This range offers a basic accuracy of 0.1% to 5%, depending on the set resistance value.
The M191 Insulation Tester calibrator is complemented with additional electronic circuitry, allowing not only the calibration of resistance ranges, but also the calibration of test voltages generated by UUT, short-circuit current verification, checking the functions for measuring the dielectric parameters such as polarization index (PI), dielectric absorption ratio (DAR) and the polarization ratio (PR). The calibrator also allows verification of the timer function of UUTs.
The calibration can be operated manually using the front panel keyboard or in remote mode using one of the two interfaces GPIB or RS232. The calibrator is supported by CALIBER software.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
