Many precision test-and-measurement and high-speed analog applications require an exact targeted voltage to be delivered to the device under test or intended load to accurately analyze the device.

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

A thorough understanding of Delta and Wye service transformers, their primary and secondary windings, and their windings’ voltages, will help HVACR service technicians in their understanding of ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Some industrial applicationsrequire you to feed a low-powerdc/dc converter from a three-phasesource and possibly to deal with line-tolinevoltages of 200 or 400V rms.Further, the neutral terminal of ...
