Abstract

This paper presents a digital instrument for the power quality analysis in systems where voltage or current waveforms are non-sinusoidal. It is based on a C40 DSP and on a special high-speed data acquisition system. The analysis is performed by a recursive algorithm which allows the mutable system properties to be tracked. The paper also goes on to discuss the performance of an instrument prototype, both in terms of accuracy specifications and speed of measurement
