Скачать или смотреть Harmonic mitigation techniques - AFE vs passive filter

When addressing harmonics in your building electrical system, different mitigation methods are available. This video compares variable frequency drive Active Front Ends (AFE) and drives installed with a passive filter installed on the input power. There isn't always a clear winner and usually you'll have to consider when to use either technology.
