Study of the Harmonic Distortion (THD) and Power Factor Oriented to the Luminaries Used in the Traffic Light System of Bogotá City, Colombia

摘要

In order to achieve a "healthy" power system, it is important to monitor existing values of electromagnetic interference, focusing on the quality of permanent technical products in relation to the phenomena present in the power grid. In this study harmonic distortion measurements are made in the voltage wave (THDv) and in the current wave (THDI) in order to determine the levels of harmonic distortion and power factor in the luminaries system that compose the current traffic light system (LED and halogen) in Bogota. Besides, this study contrasts the measurements found against the technical levels of THD both for voltage and for current, for each kind of luminaire recommended in the IEC 61000-3-2.
