  • Publication number: 20200076512
    Abstract: Isolators having a back-to-back configuration for providing electrical isolation between two circuits are described, in which multiple isolators formed on a single, monolithic substrate are connected in series to achieve a higher amount of electrical isolation for a single substrate than for isolators formed on separate substrates connected in series. Discrete dielectric regions positioned between isolator components forming an isolator provide electrical isolation between the isolator components as well as between the isolators formed on the substrate. The back-to-back isolator may provide one or more communication channels for transfer of information and/or power between different circuits.

  • Patent number: 9524223
    Abstract: Identifying an inter-relationship between performance metrics of a computer system. It is proposed to convert performance metric signals, which represent variations of performance metrics over time, into quantized signals having a set of allowable discrete values. The quantized signals are compared to detect a correlation based on the timing of variations quantized signals. An inter-relationship between the performance metrics may then be identified based on a detected correlation between the quantized signals.

  • Patent number: 9391450
    Abstract: A new type of superconducting fault current limiter is disclosed, which can advantageously be used with high voltage transmission networks. The circuit is electrically connected to two terminals, which connect to the transmission network. The superconducting circuit is located within an enclosure or tank, which is electrically isolated from ground. Therefore, the voltage difference between the enclosure and the superconducting circuit, and between the enclosure and the terminals are significantly less than exist in current deployments. In some embodiments, the enclosure is electrically connected to one of the terminals, while in other embodiments, the enclosure is electrically isolated from the terminals. The circuit can be combined with other like circuits to address a wide range of current transmission network configurations.

  • Patent number: 9121879
    Abstract: Techniques for improving reliability of a superconducting fault current limiting system (SCFCL) are provided. In one particular exemplary embodiment, the technique may be realized as a method of improving a reliability of a superconducting fault current limiting system (SCFCL), the SCFCL system comprising a superconductor provided in a container. The method may comprise providing one or more sensors capable of detecting a fault current proximate to the superconductor; determining a change in the condition of the superconductor as a result of the fault current; and estimating the lifetime of the superconductor based on the change in the condition of the superconductor.

  • Patent number: 8914085
    Abstract: A superconducting fault current limiter (SCFCL) includes a cryogenic tank defining an interior volume, a superconductor disposed in the interior volume, and a voltage detector configured to detect a voltage drop across the superconductor and provide a voltage signal representative of the voltage drop. This voltage detector enables real time monitoring of a condition of the superconductor during steady state operation of the SCFCL. If the voltage drop exceeds an acceptable voltage drop, corrective action such as maintenance, repair, and/or replacement may be taken.

  • Patent number: 8739396
    Abstract: Several embodiments of a novel technique for limiting transmission of fault current are disclosed. Current power distribution systems typically have an impedance, or reactor, on the output of the network equipment to limit current in the case of a fault condition. A low resistance switch, which changes its resistance in the presence of high current, is connected in parallel with this reactor. Thus, in normal operation, the current from the power generator bypasses the reactor, thereby minimizing power loss. However, in the presence of a fault, the resistance of the switch increases, forcing the current to pass through the reactor, thereby limiting the fault current.

  • Patent number: 8718733
    Abstract: A superconducting fault current limiter recovery system includes a superconducting fault current limiter, a shunt electrically coupled in parallel with the superconducting fault current limiter, and a bypass path also electrically coupled in parallel with the superconducting fault current limiter. The bypass path enables a load current to flow through the bypass path during a bypass condition. Thus, load current may be quickly reestablished to serve loads after a fault condition via the bypass path while a superconductor of the superconductor fault current limiter has time to return to a superconducting state after the fault condition.

  • Patent number: 8654486
    Abstract: A SCFCL system includes a first SCFCL, a second SCFCL, and a controller configured to control at least one switch to couple the first SCFCL to a power line between an AC source and a load, and to electrically isolate the second SCFCL from the power line during a first operating mode when the first SCFCL is in service and the second SCFCL serves as a spare. During the first operating mode, the second SCFCL, may be maintained in a latent standby state or an immediate standby state. The second SCFCL may be automatically switched into service to provide for fault current protection in case the first SCFCL needs to be taken out of service for maintenance, repair, or replacement.
