The role of the switchgear in a hydroelectric power plant is to connect electricity generation with the power grid. Periodic inspection of the switchgear and its components is crucial for maintaining the operation of the power plant. The main components of a switchgear include busbars, insulators, disconnectors, fuses, circuit breakers, measuring transformers, and surge arresters, as well as sulfur hexafluoride (SF6) used as an insulating medium. Gas-insulated switchgear is crucial for the safe and reliable transmission of high-voltage electrical energy. The most commonly used equipment in this area is the 8DN9 type gas-insulated switchgear, which is employed for the distribution of electrical power in high-voltage systems. The analysis pays special attention to the hydroelectric power plant Rama, including its construction, technical characteristics, and operation of the switchgear. The analysis presents the protection and control system, focusing on the protection of transmission lines, transformers, and busbars, as well as the technical characteristics of the protection systems.
