Abstract: A system includes a vessel containing a crude oil inlet for introducing crude oil into the vessel; a fixed super-hydrophobic mesh subsystem comprising a fixed super-hydrophobic mesh; an inductor cup set system comprising at plurality of inductor cups, each of the plurality of inductor cups comprising a primary coil and a secondary coil, the inductor cups to determine an amount of water in the crude oil based on a comparison of the induced voltage between the primary coil and the secondary coil; a movable super-hydrophobic mesh subsystem comprising a super-hydrophobic mesh coupled to at least one stepper motor, the stepper motor to rotate the mesh by a predefined angle based on the comparison of the induced voltage determined by the inductor cups; and a metal grid subsystem comprising a metal grid electrically coupled to a transformer residing outside of the vessel, the metal grid to electrostatically dehydrate the crude oil.

Abstract: An over-voltage protection system is provided for use with electrical equipment. The system includes a protection circuit having a first bus for receiving electrical power, a second bus for providing power to the equipment and two parallel surge arresters connected between the first bus and ground. A main and backup bushing are arranged in parallel between the first and second bus. The main bushing is arranged in series with a normally closed contact maintaining the main bushing in service by default. The backup bushing is arranged in series with a normally open contact isolating the backup bushing by default. The protection circuit comprises a controller for testing the insulation of the arresters and bushings. The controller is configured to selectively actuate the contacts to selectively isolate, or incorporate, the arresters and bushings in the circuit to facilitate testing and maintenance while maintaining the protection circuit operational.
