  Harmonic Distortion Responsibility Attribution between Utility and Specific Low-Tension Costumer - Case Study
  Author(s): Lugo AJLugo AJ
  
  The Electric Power Quality studies the electromagnetic phenomena that can cause disturbances in the electrical systems, which can be of permanent regime (steady state voltage, power factor, harmonics, voltage unbalance, voltage fluctuation, frequency variation) or transient voltage variations). With the technological advance in the area of power electronics, an increase and diversification of the amount of appliances that need electric energy for its operation is occurring. These devices (non-linear loads) produce distorted (ie non-sinusoidal) current, even when powered by a sinusoidal source, and can also distort the voltage at the connection point with the utility. These distortions are called harmonic distortions of current and voltage and are classified as permanent regime perturbations. As harmonic distortions cause several problems in the various consumers connected to the elect.. Read More»
