Title:
TECHNIQUE FOR LIMITING TRANSMISSION OF FAULT CURRENT
Document Type and Number:
WIPO Patent Application WO/2010/151583
Kind Code:
A3
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 (144, 146), which connect to the transmission network. The superconducting circuit (120) is located within an enclosure or tank (112), 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.
