Active Harmonic Filters (AHF) Harmonic currents are caused by non-linear loads connected to the distribution system. A load is said to be non-linear when current it draws does not have same wave shape as the supply voltage. The flow of harmonic current through the system impedances causes voltage distortion in the distribution system. Following are … Read more
