Abstract: Nowadays, a clear trend of increase of system voltage to 800 kV AC and above can be observed in the world. This calls for the need of having test facilities to verify the fault current ...

Circuit breakers are at the heart of every modern power system. To ensure the systems are properly protected, it’s essential the breakers should operate correctly when called upon to do so. This means ...

There are a number of complex tasks involved in the manufacturing of electronic assemblies, all of which can go wrong. In order to ensure quality standards are met, the fabrication of the printed ...

Wherever circuits need protection against current overloads or short circuits, you’ll find circuit breakers. They range from fingernail-sized devices for semiconductor protection to truck-sized ...

THE Electrical Research Association has recently reported an interesting development which has taken place in connexion with its programme of research on gas blast circuit breakers. Normally the ...

Low-voltage circuit breakers are predominant in virtually every electrical power system. Several years ago, Shermco Industries surveyed NETA-accredited companies for the IEEE Electrical Safety ...
