The new RMIS resistance meter from Elettrotest can measure the resistance of the windings of a motor driven by a pulse width modulated (PWM) power supply. This can be done on a single-phase motor as well as a three-phase motor with a maximum voltage of 500Vac.

Specifications

Using the resistance method, the RMIS can directly measure the resistance of the coil windings and obtain accurate resistance values without turning off the power. This for resistors in the range of 2 ohms (resolution 1m ohms) to 2000 ohms with an accuracy of 0.5%.

It is also possible to show the temperature graph of the motor on the large touch screen colour display. The unit is suitable for measuring both Asynchronous motors (single phase and three phase) and brushless PMSM motors.

For additional information about the RMIS Resistance Meter please refer to the brochure. Or contact one of our consultants.

ABB

"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."

University of Luxembourg

“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.”
