Abstract

The scope of this paper is the presentation of Electromagnetic Compatibility (EMC) in relation to the interference caused by surge voltages. For this purpose, the EN 61000-4-5 Standard has been instituted, describing the procedure of testing and verification of a device for immunity against surge voltages. The investigation of the above mentioned immunity is very important, as surge voltages are a very common and usual phenomenon. Their causes are either natural (lightning) or man-made (switching transients). Specifically, an investigation of the test set-up defined by the EN 61000-4-5 Standard was made. The simulation by computer of the coupling network located between the device under test and the power supply network was done using the PSPICE program and a 3-phase coupling network was constructed. Measurements and tests were performed. This construction and also the methodology described can become a useful tool for anyone who wishes to perform simple tests to a device for immunity in surge voltages according to the mentioned Standard.
