This whitepaper discusses the factors that need to be considered when selecting rated currents of circuit breakers.
Thermal circuit breakers for equipment (CBE) protect motors and transformers against electrical overloading. The trip release of a breaker takes place with the deflection of a bimetal. This deflection...

Why is it that seemingly similar power supplies have significantly different performance and reliability characteristics? The answer may lie in the specification detail that can be missing from some data sheets, available only in the long-form data/application notes or may even be due to “specmanship”.

This paper presents the modeling results for prediction of thermal performance using synthetic jets ejectors. A synthetic jet is an intense, small-scale turbulent jet synthesized directly from the fluid in which it is embedded. A jet ejector consists of a primary high momentum jet inducing a secondary flow within a channel....
