The use of renewable energy sources in the power supply systems of selected level crossings devices

The problem of ensuring safe traffic of rail and road vehicles at rail-road level crossing is one of the most important issues of safe land communication. The article presents types of technologies that were used in the presence of installed automation devices at rail-road crossings. The estimated energy consumption for new, energy-saving solutions is presented. On this basis, a strultura was adopted for powering photovoltaic panel devices. For this solution, a method of implementing overvoltage protection has been proposed.
