Harmonics demonstration panel

       

Have you seen DKI's demo panel yet where we demonstrate the origin and effects of neutral conductor loads through harmonics? Here you can choose to use incandescent lamps, dimmed and without dimmer, and compact fluorescent lamps being operated in single-phase, two-phase and three-phase modes. The currents in each of the 4 conductors is measured twice, once by a moving coil meter (equipped with a B2 rectifier bridge) and once by a moving iron meter. Supplementary to this, the neutral current has to pass through a loudspeaker.
