A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up ...

A new theory could help build future superconducting alternating-current fault-current limiters for electricity transmission and distribution systems. The work identifies design strategies that can ...

Schematic view of a typical Smart Cable Guard setup with a monitored cable section spanning multiple RMUs installed in medium-voltage/low-voltage substations. Medium ...

An electrical arc flash can occur when someone is verifying the presence of voltage, checking the balance of current, operating a switch, inspecting an energized cable or bus connections during ...

American Superconductor Corporation and Siemens AG announced commercial-grade performance levels for a medium voltage superconductor surge protection device known as a fault current limiter (FCL). The ...

Based on presentation to NACE Corrosion 2010 conference, San Antonio, Mar. 14-18, 2010. Currents from high-voltage direct current faults can damage underground-underwater pipelines. This type of DC ...
