Home » MI 9210A, MI type 1 ohm standard
The MI 9210A MI-Type standard was developed by Measurements Instruments after years of research by the NRCC and MI. This model is now offered as an improved resistance design to replace the L&N Thomas-Type One-Ohm standard, as well as other values.
These improvements have been achieved through a new annealing process of the element and changes in structural assembly.
Historical data now shows that the MI 9210A is the most stable oil-filled resistor commercially available. The 9210A model has a long term drift of less than 0.2 ppm per year and a temperature coefficient of less than 0.05 ppm / °C.
In every country there is only one institute that uses these kinds of standards. In the other cases a set of precision resistors is used which cover the different decades.

"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.”
