WHEN an electric generator is accidentally short-circuited, huge currents are developed and unless the ‘pcircuit-breakers’ act promptly, serious damage may be done to the generator and there is a risk ...

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 ...

On April 14, in Jinchang city, Gansu province, as soon as the command was given, an artificially simulated single-phase instantaneous grounding short-circuit arc was instantly triggered at the ...

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 ...

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 ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

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 ...
