Abstract

Everyday, disturbances in the frequency range 2-150kHz become more and more important. In order to model these disturbances, many experiments have been done to observe and record results. This work describes what is called "Measurement method standards". Three of them are very common; the IEC 61000-4-7 and 4-30, and CISPR 16-2-1. The idea is to understand how those methods work, based on which tools, in order to implement those on platform like Matlab. Another purpose of this work is to compare the different standards based on experimental signal. Different characteristics of those methods are analyzed in each chapter, to finish by a global comparison between each of them, based on different signals, such as CFL, Water Pump, PV,.... coming from different sources (Panda, Laborelec and our own measurements). This work indicates that each standard provides result, to give disturbances of signals. But, the voltage and current spectrum depend on the measurement methods parameters and the type of signal analyzed, even if the same basic tools (the FFT) is used by each standard.
