Testing circuit card assemblies (CCAs) requires a delicate balance between performing exhaustive fault detection and reining in total assembly cost. With shrinking card real estate accompanied by ...

Electrical engineers have manually identified circuit faults using multimeter testing and visual inspections, spending countless hours measuring currents and inspecting for soldering defects.

The digital voltmeter is the best basic tool for electrical troubleshooting, because it's calibrated and exact. But remember, the digital voltmeter can't detect a high-resistance fault if the circuit ...

The multi-wire branch is here to stay; so is ground fault protection. But we should unite these technologies only when it’s a good match. Ground-fault protection and the multi-wire branch circuit ...

Fault-tolerant digital circuit design is a critical field that seeks to ensure the uninterrupted operation of electronic systems even when individual components fail ...

Residential electrical branch circuit breakers incorporate electronic and electrical technology in Arc Fault Circuit Interrupters that can turn off power to prevent fires if arcing occurs. This ...

The age profile of low-voltage cable within the Northern Ireland Electricity network ranges from the late 1930s to present day, and the cable type consists of a mixture of paper-insulated ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...
