This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V. Overcurrent damage of PFC front-end boost ...

Solid-state overcurrent-protection ICs such as USB switches and card-slot power switches offer a simple and robust protection for pins at risk of overloads and short circuits. Such switches, however, ...

Lightning, inductive load switching, or capacitor bank switching may cause transient overvoltage conditions in AC line voltage applications such as white goods and appliances. Metal Oxide Varistors ...

The overcurrent protection requirements outlined in the NEC can be found in Art. 240, except as noted in Table 240.3. As we noted in Part 16 of our series on Electrical Services, the requirements for ...

For modern distribution protection, Negative Phase Sequence (NPS) Protection is often relegated in favor of common elements such as Overcurrent (OC) or Earth Fault (EF), but NPS is an incredibly ...

All questions and answers are based on the 2017 NEC. Q. Per the NEC, overcurrent protection devices must be placed at what location in branch-circuit or feeder conductors? A. Except as permitted by ...

As the electric distribution system transforms into a smarter network, Commonwealth Edison Co.’s distribution automation team has embarked on a step-change journey that will transform distribution ...
