Green transformers, a sustainable and environmentally-friendly range of power transformers, are gaining in popularity. The growing interest in such transformers is linked to the introduction of innovative technologies, such as natural esters (biodegradable and renewable liquid offering higher fire safety) combined with a sealed design, to be used instead of classical mineral oil. For efficient and accurate moisture-condition monitoring, green transformers need moisture-equilibrium charts. In-depth experiments have been carried out to produce and validate such charts, similar to those existing for mineral-oil-filled transformers.
