Measurements and Modeling of Neutral Harmonic Currents on the Education Office Building
초록
With the proliferation of nonlinear loads such as personal computers in an educational office building, high neutral harmonic currents have been observed. High neutral currents in three-phase four-wire distribution power systems can cause overloaded neutral conductors, overloaded transformers, voltage distortion, common mode noise, and malfuntion of protective equipment. On-site measurements of harmonic currents and voltages were made and the corresponding equivalent circuits was developed. The circuit model under study was simulated numerically and graphically through the use of the software MATLAB.
