TLDR
The zigzag transformer is one of the solution to attenuate the neutral current and reduce the zero sequence harmonic currents of the distribution systems.Abstract:
The three-phase four wires low voltage supply system to residential, commercial and production areas in the distribution system is implemented. The different nature of loads connected to the three-wire four-phase distribution system. It can be personal computers, automatic machines, variable speed drives, lighting ballasts and other electronic power equipment, which may produce a nonlinear characteristic cause zero sequence current to flow in the system in the neutral of supply system. This may cause a serious power quality problems, results in reduction. This paper present to reduce the harmonics currents and neutral overloading by using the zigzag transformer. The zigzag transformer is one of the solution to attenuate the neutral current and reduce the zero sequence harmonic currents of the distribution systems.read more
