A poor quality power causes large losses to society. Thus it is used an equipment named power quality analyzers for magnitude measurement of these disturbances and determine the causes of these abnormality. The principal problem with these devices is the high cost and they usually are imported that invalidates multipoint measurement of client’s electrical system. In this scenario, this work aims to provide support and alternatives for the development of power quality analyzers, which consists of a set with voltage and current sensors and a central processing module. In the development of any sensors or instrumentation there are difficulties on signal conditioning generated from the used component’s electrical characteristics and principally...
