<p>Stationary inductive apparatus, especially an electrical transformer, comprises a core (11) surrounded by electrical windings (12) and contained within a tank (10) in which the windings are provided with a container (14) having an at least partially opened top to contain dielectric and coolant fluid; a fluid lift pump (15) is provided to raise liquid from the bottom of the tank to the container; and the tank is connected to an external condenser (18) located at a level above that of the windings so that coolant liquid vapour may pass from the tank to the condenser and, having condensed therein, be returned (under gravity) to the container (16) surrounding the windings.</p> |
