Teed lines are widely used in rural power networks in China. The paper theoretically analyzes the voltages and currents when a single line-to-ground fault occurs, constructs a new mathematical model for fault location on the teed lines, performs corresponding MATLAB simulations. Simulation results show that currents near the source (bus M) are almost independent of fault positions and fault res...

Recently, since single phase loads and dispersed generators become widespread, unbalanced voltage in distribution line become an important problem for voltage management. One of them is that the control of a conventional voltage regulation device become difficult because of the difference of the magnitude of the line voltages, the other one is increase of 3rd harmonic voltages. The authors prop...

AC interference from high voltage power lines can constitute an electric shock hazard and a threat to equipment integrity during both load and fault conditions. Mitigation systems are usually installed to reduce the touch voltages so that the nearby metallic utilities are safe. This paper discusses the states of the touch and step voltages for a few typical right-ofway systems under load and fa...
