Senior engineering technician Edward Browne prepares to test a breaker Wednesday morning as Underwriters Laboratories unveiled its new short-circuit lab in Camas. The lab can send enough amps through ...

So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...

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 ...

This internal short circuit device provides a controlled method of testing to improve the safety of lithium-ion batteries in space gear and electric-drive vehicles. The statistics for shorts occurring ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

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 ...

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 ...

Simple construction allows an open-loop Hall effect sensor to beat its closed-loop counterparts in terms of price, weight, and size; yet it may be susceptible to temperature variation and saturation.

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 ...
