Study of Electromagnetic Compatibility of a Voltage Sensor Based on a System of Galvanically Coupled Bodies with a Wireless Energy Transmission System

The growing digitalization of energy systems requires the creation of new approaches to the construction of systems for measuring high voltage power lines. The design of a voltage sensor based on a system of galvanically coupled bodies with power supply to the electronic unit of the voltage sensor from a wireless energy transmission system is considered. An approach is proposed for assessing the electromagnetic compatibility of the electronic unit of the voltage sensor measuring element with a wireless energy transfer system. The results of the analysis of the electromagnetic compatibility of the power supply system of the electronic unit of the voltage sensor using the method of wireless energy transfer from the perspective of the conditions for ensuring their joint operation are presented. The results of computer and finite-dimensional modeling of the proposed measuring system are presented, confirming the possibility of practical implementation of a wireless power supply system for electronic units of voltage sensors. Recommendations are given on the best geometric location of the electronic unit of the voltage sensor relative to the receiving coil of the wireless energy transmission system.
