This paper presents an adaptive protection algorithm that adjusts the tripping characteristics of the differential relaying schemes in response to changes in CT saturation levels and DC component ...

Power transformers play a critical role in electric power systems by facilitating connections between subsystems with different voltage levels. Ensuring their reliable operation and protection against ...

GE Digital Energy has announced the Multilin L30 Line Differential System, which delivers cost-effective current differential protection for high-speed, sub-transmission and distribution lines and ...

Cooper Power Systems has designed its full-featured differential relay, the iXP-420, to provide comprehensive two-winding transformer protection, and monitoring and control. The iXP-420 incorporates ...

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 ...
