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 ...

Schweitzer Engineering Laboratories, Inc. has announced three new additions to the popular SEL-787 family of differential protection relays, providing low-cost, versatile transformer differential ...

Abstract: This paper introduces a new generator differential protection strategy using small vector method. When a generator is wrong, the temporary current contains multiple frequencies. Given the ...

Abstract: Inverter-interfaced distributed generators (IIDGs) introduce a major challenge for the protection of inverter-based islanded microgrids (IBIMs) due to their limited fault current ...

Thanks to ongoing innovations in technology, electrical engineers' approach to motor protection has changed over the years. The traditional strategy to large AC motor protection (e.g., over 500 hp), ...
