The Chroma 66205 is the second generation of the 66200 series power meter, specially designed for one channel measurement. Its advanced design is capable of providing highly accurate power measurements to meet the requirements of IEC 62301/EN50564 standards. The Smart Range feature is one of the most important new features of the 66205 power meter. Smart Range makes it possible to perform active power measurements in power integration mode with the measuring range in automatic mode. The 66205 automatically selects the correct range based on changes in the measured voltage and/or current and ensures the best accuracy when integrating the measurements over time.

This power meter offers 10 selectable current measurement ranges from 5mA to 30A. External sensor options A662017~A662020 are available to extend the current measurement range. Six selectable voltage ranges are available up to 600V. External sensor option A662012 can be used to extend the voltage measurement range up to 1.2kV. The 66205 power meter is designed to comply with the IEC 61000-4-7 standard. In addition to harmonic measurements, the 66205 can also accurately measure subharmonics and interharmonics.

For remote control, the 66205 offers four types of communication interfaces, including GPIB, USB, RS-232 and LAN (optional). Using the soft panel, it can create full test reports and perform both power and regularity tests. In addition, the STORE function records the measured values and saves them to a USB storage device. The limit function can be used for production testing by performing GO/NG tests on the upper and lower limits of voltage, current and power parameters; in addition, when using the I/O port, this function can be integrated into automated production. The 66205 is ideally suited to the demanding tasks of R&D, production and quality control.

"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.”
