A water capacitor is a device that uses water as its dielectric insulating medium. A capacitor is a device in which electrical energy is introduced and can be stored for a later time. A capacitor consists of two conductors separated by a non-conductive region. The non-conductive region is called the dielectric or electrical insulator.
The water for use in water cooled capacitors should be chemically neutral, mechanically pure, and its electrical conductivity should not exceed the value specified by the manufacturer, typically 500µS/cm. The performance characteristics of water cooled capacitors are significantly dependent on the stability of the cooling water supply system.
The effectiveness of water cooling is dependent on the properties of the water used. The water for use in water cooled capacitors should be chemically neutral, mechanically pure, and its electrical conductivity should not exceed the value specified by the manufacturer, typically 500µS/cm.
In most modern water cooled capacitors, the cooling medium passes through the interior of the component. These modern water-cooled capacitors are more efficient compared to their predecessors. There are various ways of achieving cooling in water cooled capacitors. The most commonly used designs are transverse cooling and foil cooling.
Capacitors with integrated water cooling systems are suitable for such applications. Using water cooled capacitors also helps to reduce the cost and the number of components used. Film and ceramic capacitors with integrated liquid cooling systems are increasingly becoming popular for high-current applications.
Electrolytes containing ethylene glycol (EG) or boric acid are used mainly in medium to high-voltage electrolytic capacitors at temperatures of up to 85°C. In this case, the water content in the electrolyte is approx. 5-20% and inhibitors (chemical inhibitors) are used to prevent the aluminum oxide layer being negatively impacted by the water.
