EM Energy Solution with great Success in South Korea
20 Feb, 2020
had several installations of our units at different locations in South Korea.
The results and feedback have been amazing. We have proven our units unique capabilities in terms of energy reduction, improved equipment performance and a much more reliable electrical system.
on type of system, equipment connected and incoming power quality we documented
energy savings between 5-17% !!
On one of
the locations we installed our units this savings corresponded over 20 000
We used an oscilloscope to document the ability of our unit to mitigate voltage spikes and transients. At several of the locations, vast amounts of noise in terms of fast switching transients up 300 – 500 volts peak were present. After installation of our units, not a single spike was detected.This improvement will have a significant impact on the electrical equipment’s lifetime, especially regarding electronics and control systems.
The harmonic distortion was reduced well below the industry standards (EN 50160) at all locations. On one occasion, our unit was installed on a transformer system containing a high-frequency arc-furnace used for casting metal. The total harmonic distortion (THD) was peaking at 23% without the AVE installed. The AVE reduced the harmonics down to an acceptable level of 6-7 %.
One of the best aspects of our success in Korea was to see the tremendous effect that improved power quality has on equipment and machine performance. At Samsung Heavy Industries, the bad power quality resulted in a poor weld quality, which caused substantial extra work and additional man-hours. With these results, we have proven that by installing our units, customers can save significant amounts of energy and costs, which will help them to achieve a reduced carbon footprint and give them a leading-edge.
