Nowadays we are using more and more electric and electronic devices. However, we also have increasingly electromagnetic disturbances. Electronic devices are required to test electromagnetic compatibility (EMC) to ensure reliable work and not cause interference to other equipment. One of them is a series of electrical fast transients. The popular name of them is burst. It is a broadband pulsed disturbance occurring very quickly (of the order of a few nanoseconds), having a low energy charge but a high repetition rate. The standard which describes them is PN-EN 61000-4-4. Checking for resistance to them is mandatory in the EMC test procedure. For example, these disturbances arise in low-voltage electromechanical switches. This disturbance is accompanied by sparking, which in the literature is called showering arc. This research focuses on theoretical analysis, numerical analysis, and exponentiation verification with low-voltage electromechanical switches. The result of this work will be to propose better attenuation solutions. To verify disturbances, it was necessary to design and build a test bench with low-voltage electromechanical switches to observe EFT/burst and check attenuation solutions. I will present theoretical background, test bench and progress in my research work.
