Electric power quality or simply power quality involves voltage frequency and waveform. If the Power Quality of the network is good then any. If there is one universal factor that can and will disrupt microprocessor-based controls and cause downtime it is power quality. There is no such thing as perfect power quality in the real world. Electrical Power Systems Quality Second Edition. The information is presented without heavy-duty equations making it practical and easily readable for utility engineers industrial engineers technicians and equipment designers.
