There are many benefits to using the latest protective relays available in the market. Fast communication and better system protection are two such examples. This article explores both concepts about source synchronization for generator paralleling schemes. To meet the requirements for large-scale electrical distribution systems, multiple generators often need to be paralleled (operate in tandem). Hence, the synchronization of generator sources becomes a very important aspect when multiple gene...

Even after a legacy of supporting technologies, energy harvesting (the ability to scavenge energy from any source that physics affords us) has only graduated from emerging to emerging. This can be attributed to the drastic reduction in system power budgets resulting from Moore’s law and MEMS.  Can users imagine an entire sensor network, processor, and wireless communication (including a display!) with a system power budget of only a few milliwatts? Users no longer have to. Waste vs....
