For utilities, proper protection against high voltage transient overvoltages and overloads is critical to ensure maximum life of their power transformers. Failure to do so can result in significant ...

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

Requiring only a handful of inexpensive components, the circuit breaker in Figure 1 responds to both overcurrent- and overvoltage-fault conditions. At the heart of the circuit, D 2, an adjustable, ...

The Barrington Model Circuit Breaker Simulator was designed to be a convenient, lightweight alternative to operating high-voltage circuit breakers while testing the operation of substation protection ...

Solid−state circuit breakers using SiC devices are particularly well-suited for protecting next-generation power systems.

The multi-wire branch is here to stay; so is ground fault protection. But we should unite these technologies only when it’s a good match. Ground-fault protection and the multi-wire branch circuit ...
