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 ...
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 ...
A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...
Analog circuits, despite constituting a small proportion of overall electronic systems, account for a substantial share of system failures. Consequently, the development of robust fault diagnosis ...
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 ...
Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...
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 ...
