A theoretical back- ground discussion of various pieces of equipment and their signicance to har- monics is included. National Electricity Regulator (NRS 048) standards are discussed with refer- ence to performing a basic investigation and short comings. A test study was performed on the Brandspruit Mine in Secunda. ATP models are developed for equipment relevant to the test case, these in- clude AC{AC converters, AC{DC converters, three phase transformers and cables. Finally the measured test case is compared to simulation results and conclusions drawn.2341270 bytesapplication/pdfenharmonicsATPmodellingvariable speed drivesVSOThesis
