AI summary

A system and method are described for regulating water concentration in a dielectric fluid. The system can comprise electrodes capable of applying an electric field across the dielectric fluid, thereby causing charge carriers and water included in the charge carriers to move toward a respective electrode. The system further includes a trap positioned near the electrodes and comprising a water absorbing material capable of trapping water, thereby reducing the concentration of water in the dielectric fluid. It is also possible to measure properties of the dielectric fluid and use such measurements to control the water-trapping process.
