Three Phase Filter (no neutral line) for Renewable Energy (Wind Generation)
Renewable energies are now becoming an ever-growing alternative to generating electricity. This is the case of power generation through windmills. The power injection on the network must be done cleanly; this means that the power generating must inject it with RF noise free. The radio frequency noise that typically range from 10kHz to 30MHz is unintentionally injected into the network and therefore requires the use of an appropriate filter element: this is both the......14/11/2011
