Interlaboratory Comparison of Electromagnetic Fields in Power Supply Systems

This interlaboratory comparison is performed for two reasons: to ensure the repeatability of testing amongst EMC laboratories concerning specific test methods and to evaluate the testing capabilities of these laboratories. The purpose of this paper is to present the application of an interlaboratory comparison method for electromagnetic fields produced by power supply systems, involving two laboratories. An electromagnetic field generator with a frequency of 50 Hz, which is moved from one laboratory to another, is used in order to obtain the data for the final assessment. The results obtained were based on the three-point measurement method in accordance with the standard IEC 61786.
