Electromagnetic compatibility and security requirements in the construction of prototype, low voltage, research devices

The article presents the standards harmonized with the EMC and LVD directives, and procedures leading to the fulfilment of these requirements when designing prototype, research devices. It describes the methods of limiting interferences conducted to the power supply network and ensuring proper impedance grounding. This article also shows the necessity to analyse all the problems which may arise in connection with the EMC and LVD directives at the design stage as well as the need to conduct the designers’ testing during the construction of equipment.
