This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...

This Design Idea presents a low power short circuit finder that capitalizes on the ear’s sensitivity to changes in frequency. The heart of the circuit is a voltage-to-frequency converter (based on ...

What's the difference between a short-circuit current rating (SCCR) and an interrupting rating (IR)? If you're not sure, clearing up the confusion could be as simple as brushing up on your definitions ...

The sample tester in Figure.1 Detects short circuits on assembled pc boards and also rings out cables and harnesses. The sample tester in Figure.1 Detects short circuits on assembled pc boards and ...

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...

Reviewing a typical protective device trip curve (click here to see Fig. 2), it can be divided into three regions. First is the “instantaneous region,” which is the region intended to interrupt ...

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 ...
