For various applications, we often want to measure currents accurately. And for currents up to 10A, this can often be done just fine with a DMM. Most power analysers have a direct current input that can measure up to 20A. Some even 30A and exceptional are the analysers with a direct current input of 50A AC or DC.
With ampere clamps, we can measure much higher currents, but then the accuracy is often disappointing. This is usually limited to 1% and the better ones to 0.5%, but that’s about it.

With our range of accurate power analysers, we naturally want to measure more accurately. Most analyzers are at 0.1% or better, with an outlier up to 0.02%. With specific shunts, we can also measure high currents to about 0.01% accuracy.
With zero flux sensors, however, we go to higher accuracies (0.001%) and usually also with a higher frequency range (max 2MHz). And this in a current range from 60A to max 2000Arms.

With Newtons4th’s LEM-6 interface module, these zero flux sensors can be easily connected to a power analyser so that accurate measurements can also be made at high currents.

For detailed specifications, please refer to the datasheet of the LEM-6.

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.”
