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 ...

Most modern power-supply control ICs offer built-in overcurrent or short-circuit protection. While some overcurrent-protection schemes are latching, others are nonlatching. When the overcurrent trip ...

For the PDF version of this article, click here. Protecting power transistors against overcurrent failure has always been a challenging issue in power circuit design. In order to protect against even ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

As the electric distribution system transforms into a smarter network, Commonwealth Edison Co.’s distribution automation team has embarked on a step-change journey that will transform distribution ...

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 ...
