Differential protection is best understood as a fault control philosophy rather than a component category. The relay itself is secondary to the scheme it enforces. Once a zone is defined, the system ...

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 ...

HARTING has added a differential current transformer capable of carrying out current measurements at up to 10 A to its family of current sensors for industrial applications. Specifically designed for ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

Certain electromagnetic devices such as differential transformers are effective at translating the displacement of a magnetic armature into an AC voltage, which is a linear function of the ...
