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.

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 ...

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 ...

Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

AC line monitors measure the real-time quality of power delivered to a given load. These devices are diverse in capabilities, measurement accuracy and cost with systems ranging from simple, ...
