For measuring ac current in single- and three-phase energy management systems, switchboards, and generator and telemetry controls, the 4-kV-isolated M100 series ac current transducers convert ac ...

The APT-TH Series Power Transducers monitor watt consumption of three phase loads. They provide an analog signal proportional to the active power consumed by the monitored load. The three current ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

NK Technologies introduces APT Series Power Transducers. The APT measures three phases of current and voltage and produces an industry standard analog signal proportional to the watts used. The ...

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 ...

Many older industrial facilities use single-phase, oil-filled transformers made for pole-mounting but installed at ground level to create 3-phase power distribution systems. Usually, primary and ...
