3-In-1 Condition Sensor For Oils

IMG 20230104 WA0036

The existence of moisture lowers the breakdown voltage of insulating oil, increases the dielectric loss and accelerates the degradation of polymer insulation aging. Thus reducing the performance of the insulation system and even cause insulation breakdown and partial discharge.
