The design and construction of a power quality parameters recorder

The paper presents the authors´ approach to design and construction of power quality parameters recorder conforming the requirements of IEC 61000-4-30 standard. The recorder was designed and built according to the measurement algorithms developed by the authors. Modeling of the applied algorithms and analysis of their sensitivity to variation in some parameters were carried out in a Matlab-Simulink environment. Algorithms for measuring modules were subjected to comprehensive tests verifying their correctness.
