A commercially produced three phase power line filter is submitted to a Current Barrier (CB) Electro-Magnetic Compatibility (EMC) zoning strategy as an attempt to confine high frequency common mode currents. The intent of the paper is not to show how to build a ‘perfect’ filter, since this is known. The paper is about understanding why a theoretically high quality filter in practice can still fail...
When testing large stationary equipment for EMC compliance, on-site testing is often the only option. In case of a fixed mains connection, use of an artificial mains network is problematic. Within In the framework of an European Research project on EMI testing of large installations, research has been performed on the performance of new and existing alternative methods. While researching existing...
Modern photovoltaic (PV) installations are being installed in large numbers. Manufacturers are using different harmonized standards to show compliance with the legislative requirements such as the European EMC Directive. Their selection of harmonized standards is not based on adherence to (essential requirements of) the European EMC Directive, but more on what is most convenient, i.e. lowest cost;...
Modern so-called energy efficient equipment often draw current only during a very short period of the period of a power supply mains. This is causing unwanted non-sinusoidal and harmonic currents. In some cases even a single diode is used for rectification causing direct current (DC) in the mains supply. To reduce dissipation the semiconductor components switch very fast, which is causing interference,...
