Remote Powering over communications cabling (part 3)

Remote feeding is a technology which enables operators to power several remote sites from a central location.  Remote powering implies that the power equipment is not local but some distance away. Remote means that the powering and powered equipment are in separate buildings or at different external locations inside same building.It can be used as

Five key considerations for east-west solar design | PV Tech

https://www.pv-tech.org/editors-blog/five-key-considerations-for-east-west-solar-design Around the world solar developers are turning array designs on their head and choosing to go east-west instead of south- or north-facing like their traditional cousins. While east-west solar arrays may have a reduced total output, the value of the electricity they produce is inherently higher in most markets – They are generating more

Finding the right power supply technology for your design | EDN

https://www.edn.com/design/power-management/4460362/Finding-the-right-power-supply-technology-for-your-design In 2016, each person on the planet purchased an average of 111 semiconductor chips or integrated circuits. As the number of chips climbs, so does the need for greater power, space, and cost efficiency. In response, power device manufacturers have continued to evolve silicon-based technologies and develop new, wide bandgap materials such as gallium-nitride

Modular LED lamps with IoT

The lighting industry is undergoing a revolution driven by LED technology. LED is is now the dominant lighting technology for all new buildings and retrofits. Yet today, only a small percentage of LED fixtures are supplied with IoT sensors installed. It was estimated 140 million LED fixtures were expected to be distributed in the United

Automatic Circuit Reclosers Probed as Potential Cause of California Fires – IEEE Spectrum

https://spectrum.ieee.org/energywise/energy/the-smarter-grid/utilities-probed-as-potential-cause-of-california-fires Automatic reclosers are pole-mounted circuit breakers that can quickly restore power after outages. Reclosers make quick work of many line faults, the great majority of which result from temporary insults such as a tree branch striking a line or the electrocution of an unlucky squirrel. Reclosers usually try restarting a line 2-3 times before giving up
