Electromagnetic Compatibility (EMC) is defined by the European Directive on EMC as the ‘ability of an equipment or system to function satisfactorily in its electromagnetic environment without producing intolerable electromagnetic disturbances to anything in that environment’. EMC means that equipment, which can be a single device or a system existing of connected devices, shall be designed and manufactured in such a way that: • the electromagnetic disturbance generated by the equipment does not exceed the level above which radio and telecommunications equipment or other equipment cannot operate as intended, and • the equipment has a level of immunity to the electromagnetic disturbance to be expected in its intended use which allows it to operate without unacceptable degradation of its intended use. The area within EMC focusing on the operation of power distribution systems including connected equipment is called Power Quality (PQ). It involves the supply and the use of electrical power and is therefore about the interaction between voltage and current. This thesis studies this interaction for the distribution network inside large user installations. It analyzes conducted interference and models the distribution network including connected equipment.
