The justification for complex practicability of applying emergency lighting and light strobe alarm on potentially dangerous sections of 10 kV power transmission lines

Recently, the low operation reliability and a high rate of electrical injuries are still very relevant problems for 10 kV overhead power transmission lines. The specialists of the emergency crew associate the problems of 10 kV power transmission lines with such terms as insulation breakdown, single phase-to-ground fault, double-ground fault, pace voltage, touch voltage. The process of finding a single phase-to-ground fault on the 10 kV power transmission lines is not only difficult, but also dangerous for the specialists of the emergency crew, especially at night-time and/or under unfavourable weather and climatic conditions. Currently, none of the technical devices used in 10 kV power lines in conditions of insufficient visibility cannot effectively alarm to the specialists about the place of a single phase-to-ground fault or double-ground fault and it cannot be used to improve electrical safety on the potentially dangerous sections of 10 kV power transmission lines. The installation of lighting devices on the 10 kV power transmission line supports can become the most efficient problem decision in such a situation. They will provide the light strobe signaling of a single phase-to-ground fault and emergency lighting on the potentially dangerous sections of 10 kV power transmission lines. Such measures will allow the specialists of the emergency crew to improve the efficiency and safety of the process of finding a single phase-to-ground fault and double-ground fault in conditions of insufficient visibility, and ensure the life safety of workers of the agro-industrial complex. These measures will radically change the negative attitude of the consumers and specialists to the power distribution network with isolated neutral and will allow to achieve a higher level of technical evolution. The article formulates the basic requirements to the lighting devices installed on the 10 kV power transmission line supports and touches upon their power supply and operating modes control.
