A poor Power Quality is among others caused by the use of Variable Frequency Drives (VFD). Speed control by the use of VFD's casuses harmonic distortion. This results is heating up wires and electronics which results in a reduced lifespan. It also causes voltage dips in the network and create inexplicable ghost failures in the total plant. The Zytec coupling is a mechanical solution whereby the power quality of the power supply is not affected.
Power Quality is invisible and there is therefore often no attention. As we increasingly non-linear devices such as inverters, LED lighting, electrical vehicles, solar panels etc to join our Power Net, Power Quality decreases. Specialized companies like Fortop see Zytec Network, measure power quality and visual this.
