Effect of harmonics on current ratings and voltage drop

... harmonic currents. Multiplying the 50 Hz conductor resistance by the appropriate factor, Cr, from the above table will give the resistance at that frequency. If Cr x Rf is substituted for Rh in equation 2 it is clear that Rf will cancel in the numerator and the denominator. Thus the factors given in ...

Ground loop (electricity)

In an electrical system, a ground loop is an equipment and wiring configuration which results in excessive unwanted current in a conductor connecting two points that are supposed to be at the same electric potential, often ground, but are actually at different potentials.Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. They do not in themselves create an electric shock hazard, the inappropriate connections merely create a not necessarily very good instance of Electrical_bonding, which is explicitly required by safety regulations in certain circumstances. In any case the voltage difference between the ground terminals of each item of equipment is small. A severe risk of electric shock occurs when equipment grounds are improperly removed in an attempt to cure the problems thought to be caused by ground loops.
