In order to ensure the safe and stable operation of power equipment and extend its service life, the humidity control scheme of power grid needs to control the humidity of substations, control rooms and other places within the safe range

Usually adopt mechanical dehumidification, rotary dehumidification, air conditioning dehumidification and other technologies, and supplemented by ventilation, sealing, moisture-proof treatment and other measures, and finally realize the real-time monitoring and effective control of environmental humidity, to ensure the safe and stable operation of the power system.
