Poor Power Quality – Causes & Solutions for Harmonic Pollution

Poor power quality – Causes and solutions for harmonic pollution

Modern commercial buildings often make an architectural statement with cutting edge design and facilities, as well as state-of-the-art systems such as stop-start escalators, air conditioning, light shows and water features. However, the drives and motors that control such systems can lead to harmonics – a type of ‘electrical litter’ that can spread on the electrical distribution system. This video explains how harmonics distort the waveform of voltage and current and can lead to malfunctioning of equipment, blowing of fuses and other electric problems. It goes on to explain ABB’s different options for resolving problems that arise from harmonics.
