Features & Benefits

The AQUAOIL 400 system is a stand-alone unit for field installation on a transformer valve. It allows the user to monitor online the relative humidity in the oil and its changes during load variation. The AQUAOIL 400 is a valuable tool in warning the following hazardous conditions:

• Ingress of moisture in transformers (through breathing system or bushing seals)
• Temporary high relative humidity conditions during cooling cycle
• Abnormal rate of paper degradation by detecting an increase of the overall moisture content in the transformer
• Detection of high water content in the solid insulation system

The AQUAOIL 400 system is used for:

• Online detection of potentially dangerous conditions coming from a sudden increase of moisture and leading to the reduction of the dielectric properties of the insulation system
• Detection of any increase or ingress of moisture in the insulation system
• Determination of the moisture content in solid insulation
• Determination of oil temperature at which water dissolved in the oil will condense
