The good ventilation of switchgear and transformer rooms | EEP· Ultimately, economic aspects such as procurement and operating expenses must be taken into account as well as the reliability (emergency power supply and redundancy) of the ventilation. At outside air temperatures of up to 30 °C, natural ventilation is generally sufficient.At higher temperatures there is danger that the permissible temperature for the equipment may be exceeded.
