Abstract: The present invention relates to an organic matter biodigester comprising a tank that has an organic matter inlet, a first connection arranged in an upper portion of the tank and a second connection arranged in the lower portion of the tank. Furthermore, said tank also has a biogas outlet and a lower surface configured to rest on a support surface. Furthermore, the lower portion of the tank is at a shorter distance from the support surface compared to the upper portion of the tank. Said organic matter biodigester also comprises a manual pump with a pump inlet connected in the second connection, and a pump outlet connected in the first connection of the tank. The pump is configured to recirculate the organic matter inside the tank from the second connection towards the first connection; and a porous layer arranged inside the tank.

Abstract: The present invention corresponds to a method and an apparatus for detecting faults in transmission and distribution systems.

Abstract: The present invention provides system for testing an electrical winding element that is usually a stator bar or a stator winding. The stator bar is attached to a short circuit conductive element to form a closed short circuit of a single turn that acts as a primary circuit. The closed short circuit is connected to a step-up transformer that will act as a secondary circuit and which has at least two turns. The step-up transformer uses a controlled variable voltage source that charges the closed short circuit. Charging the closed short circuit creates a current in the stator bar inner conductive element, causing heat on the stator bar by induction. The system of the present invention is suitable for an accelerated thermal aging test that simulates closely how heat is created by induction on stator bars of electric machines.
