Abstract
The purpose of the research is to analyze the effectiveness of the STM32 microcontrollers usage of in the implementation of the load relay protection from mains voltage surges based on the analysis of the root mean square value of the mains voltage and the detection of impulse noise. The research included: development of a projects group for various compilers, microcontrollers and software writing algorithms, as well as performance measurements of all program blocks. As a result of the research, requirements were presented for the value of the microcontroller clock frequency, which is sufficient to detect impulse noise with a duration from 10 μs. An algorithm is also proposed to reduce the requirements for the value of the clock frequency and the amount of RAM.

Keywords: relay, microcontroller, algorithm, root mean square voltage, performance.
