Purpose. Determination in the analytical form of the maximum limiting influence of the non-identity of the capacitive elements of the high-voltage arm on the amplitude-frequency characteristic and phase-frequency characteristic of the voltage divider with parallel-series connection of R-, C-elements of the high-voltage arm. Methodology. Based on the previously developed theory of broadband voltage dividers with parallel-series connection of R-, C-elements, analytical expressions for amplitude-frequency and phase-frequency characteristics of the voltage divider are obtained and investigated taking into account the limit case of non-identical capacitive elements of high-voltage arm. Results. The nature of the dependencies of the frequency characteristics of the broadband voltage divider on the value of the tolerance of the capacitive elements of the high-voltage arm, the division factor of the voltage divider in a wide range of frequency changes is determined. Simplified approximating expressions for the maximum values of frequency characteristics of the voltage divider are proposed and their error is determined. Originality. For the first time in the analytical form the limiting influence of non-identity of capacitive elements of a high-voltage arm of a voltage divider on its frequency characteristics is considered. A mathematical model of this influence is constructed and the limit values of frequency characteristics of the voltage divider are determined. Practical value. It is recommended to introduce into the normative documentation of broadband voltage dividers the corrected value of the division factor, which allows to significantly reduce the deviation of the actual value of the division factor of the voltage divider from the normalized value in a wide range of frequency changes.

The considered model was investigated according to the main characteristics corresponding to the real process (even the geometrical dimensions and electrophysical parameters coincide). It is known that a prerequisite for physical modeling is a strict geometric similarity of the model and character, as well as the equality of the corresponding similarity criteria in them. The cheapest insulator in the power industry is air. The air environment plays an important role in the design of ball arresters used in pulsed technology. In this case, it is important to measure the high-voltage voltage and obtain the exact shape of the discharge current pulse on the oscillogram. For this purpose, in this work, liquid voltage dividers were studied and the corresponding electronic models were developed. The results obtained in the electronic model are unreliable without experimental verification. The measuring equipment during the experiment gave positive results, indicating the quality of measurements, the correctness of the process of electric pulse treatment of seeds.

This research explores the crucial role of precise measurement in enhancing solar power generation efficiency within the maritime context, with a specific focus on the solar power plant aboard the PPNS Baruna 01 Crewboat. It investigates the relationship between light intensity and solar cell voltage output, affirming the direct correlation between sunlight availability and voltage generation. Additionally, the study introduces the application of simple linear regression techniques to improve measurement accuracy, particularly in voltage divider circuits and ACS712 current sensors. Results demonstrate a substantial reduction in measurement errors, from 34.88% to 0.45% for voltage measurement and from 23.71% to 2.69% for current measurement. These advancements hold significant implications for the maritime industry, promoting the adoption of clean and renewable solar energy sources on vessels, potentially reducing reliance on fossil fuels, and contributing to environmental sustainability. Moreover, the research underscores the importance of data analysis in optimizing energy systems and provides a foundation for further developments in renewable energy technology and system optimization.
