The electricity network has three main parts of production, transmission and distribution of electrical energy, the production part consist of power plants: steam, gas, wind, solar and hydropower, the transmission part which includes high voltage substations and transmission lines and the distribution part which includes medium voltage substations and Its lines are located, all of them have high sensitivity control and monitoring systems. Therefore, based on the importance of uninterrupted power supply of these systems, the use of battery chargers, inverters and industrial UPSs manufactured by the electronic power supply company will be a reliable, long-term and efficient solution.
