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 ...

Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...

In this paper, the authors present the analysis of digital differential protection for three phase power transformers. Power transformer is the key element in electrical power system. Proper ...

DALLAS--(BUSINESS WIRE)--Smaller, lighter and with a higher output power than any other comparable three-phase instrument, Megger’s new SMRT 36 smart protective relay test set is ideally suited not ...

Incident energy is directly proportional to the total arcing time. Because of this, most strategies for arc flash hazard mitigation focus on faster detection and clearing of the arc flash. The two ...

Eaton has announced the launch of a new range of power protection relays which it says are ideally suited for use in its medium voltage (MV) switchgear. The diversified industrial manufacturer has ...
