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 ...

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 ...

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 ...

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 ...

Compliance with NEC 110.10 is critical for safety. We all want safe designs, but the engineer responsible for a UPS installation may not always understand how to accommodate the UL listing unique to ...

For the PDF version of this article, including diagrams and/or equations, click here. In any off-line flyback converter design, it is possible that the output ...

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 ...

Over on his YouTube channel our hacker [Jerry Walker] repairs a Tektronix 577 curve tracer. A curve tracer is a piece of equipment which plots I-V (current vs voltage) curves, among other things. This ...
