The NOS (Dutch News Network) reports this week about damage and malfunctions in companies due to poor quality of the power.

Inverters, LED lights and variable speed drives are causing more and more interference and this modern technology is itself more sensitive to pollution of the mains.

Think of harmonics or distortion of the voltage and current forms, a bad power factor, voltage dips, interruptions and overvoltages, flicker and imbalance between the phases.

The consequences can be: the efficiency, capacity, safety and lifespan of equipment are reduced and the number of failures and failures of equipment are increased.

Fortunately, it is possible to test and measure how much disturbance is caused and how sensitive equipment is to disturbance.

For this purpose, TTMS offers programmable power supplies, loads and accurate power analyzers:

Regenerative AC power supplies
Grid Emulation
Power meters

Please also read our presentation on this subject:

“Is your design resistant to mains pollution, harmonic distortion and a bad power factor?”

TTMS advises companies and educational and research institutions in test and measurement equipment.

Together with our customers we find the best solution from a wide range of models and manufacturers.

Please contact one of the TTMS consultants for advice.

"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.”
