Title: Conservator system

Abstract: A conservator system for transformers includes a conservator tank. The apparatus is filled with oil which is saturated with a non-combustible gas. The conservator tank is connected by conduits to the top and if suitable also to the bottom of the transformer tank, respectively. The top of the conservator tank is filled with free non-combustible gas. A bag of flexible material is arranged in the top of the conservator tank and the interior of this bag is connected to the atmosphere so that it separates the oil and the gas in the tank from the atmosphere.
