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 ...

In this paper, the authors develop a program for the design of transformer using Matlab. The proposed methodology has many advantages for transformer manufacturers, since they can save design ...

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 ...

We are often asked if one ACM20 power meter can be used to measure the total current and total real power (watts) in a 3-wire, single phase, 240V AC mains supply with a neutral conductor and two 120V ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

If you’re building, renovating or planning to install a solar battery, your builder or installer might ask whether you’ve considered upgrading from single-phase to three-phase power. This upgrade ...
