ABOUT ten years ago it was found necessary to build short-circuit testing stations in order to find out the true rating for a large switch or current-breaker. In order to find out how a switch will ...

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 ...

New characterization and testing methods have been developed with respect to the state of the art in power semiconductors. Their knowledge and use is decisive for reliable and efficient simulation and ...

I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...

WE are glad to notice that the number of commercial testing laboratories in Great Britain is rapidly increasing. As a rule these laboratories are not co-operative but are set up by individual ...

Delays in short-circuit protection triggers require careful selection of the magnetics and overcurrent threshold values to prevent component stress. In any off-line flyback converter design, it is ...

Before transmission and distribution equipment is ready for commercial deployment, it must first undergo many equipment reliability, performance and safety tests, according to Newton-Evans Research ...
