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 ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

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 ...

With any switchboard or switchgear lineup, you can order ammeters, voltmeters, frequency meters, etc. These meters come with factory-installed instrument transformers, which are needed to convert the ...
