Micro grids, smart grids, small power plants in range of household size stay in the lime-light. Nowadays, smart metering system stays directly before installation. All of the above mentioned systems require complex and discrete concepts and knowledge. Definitions and use of the right concepts and correct knowledge belong to actual questions of energetics. Small size distributed power plant units, drivers, controllers and switches belong to the power plants connecting to power grids can introduce high-frequency noises. In this work the spectra and the impact of the high-frequency noises have been investigated. After analysing the measured spectra followings can be declared: High-frequency noises can trouble the Power Line Communication (PLC) system at smart metering systems. Noise can destroy propagating parameters of the useful signal affecting the safety of data communication.
