摘要： Provided is an apparatus, such as an arc mitigating device, which can include a first plasma generation device and a second plasma generation device. The second plasma generation device can include a pair of opposing and spaced apart electrodes and a low voltage, high current energy source connected therebetween. A conduit can be configured to direct plasma between the first and second plasma generation devices, such that the second plasma generation device receives plasma generated by the first plasma generation. The plasma from the first plasma generation device can act to reduce the impedance of an area between the pair of opposing electrodes sufficiently to allow an arc to be established therebetween due to the low voltage, high current energy source.

摘要： An apparatus to provide electrical coupling between two components in a well system is proposed. The apparatus includes a first component disposed around a well-bore and configured to host electrical connections. A second component is disposed concentrically around the first component and configured for power coupling with the first component. A first power coupling unit is disposed on the first component and configured to host one or more transceivers and resonators. A second power coupling unit is disposed on the second component and configured to host one or more transceivers and resonators. The transceivers and resonators on the first and second power coupling units are configured to transfer power in a contactless manner.

摘要： A dual power source pulse generator in power connection with a pair of electrodes having a first electrode, a second electrode and an air gap therebetween. The dual power source pulse generator includes a first pulse source producing a high voltage low current pulse across the pair of electrodes to allow dielectric breakdown, and a second pulse source electrically connected in parallel with an output of the first pulse source, and producing a low voltage high current pulse to thereby produce a current flow of high-density plasma between the same electrodes of the pair of electrodes in response to the high voltage low current pulse.

摘要： A multiphase current interrupter is provided for interrupting a phase current between two contacts in an electrical phase. The current interrupter includes a first ablative chamber disposed around contacts for a first electrical phase. The first chamber has an ablative material thereon that causes a shock wave when an electrical arc is generated in an arc zone for the first electrical phase during a separation of the contacts therein. The current interrupter further includes at least a second ablative chamber disposed around contacts for at least a second electrical phase. The second chamber has an ablative material thereon that causes a shock wave when an electrical arc is generated in an arc zone for the second electrical phase during a separation of the contacts therein. An interconnecting structure provides fluid communication between the first ablative chamber and the second ablative chamber. The interconnecting structure is adapted to dissipate a shock wave generated in any of the ablative chambers.
