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

Historically, typical loads of commercial power systems have been predominately linear; however, in the last few decades, a significant portion of these loads has changed to the nonlinear variety. One ...

When a plant engineer must replace bus duct at a battery charging facility, the issue of overloaded neutrals comes front and center. The plant engineer at an automobile battery-charging facility ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

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 ...

We needed to detect motion in a commercial, stepper motor driven system and subsequently initiate motion in a servomotor based system we developed. Because both systems simulate human respiratory ...

We have a number of recognized transmission and distribution experts serving on our board of "Grid Masters." Several times each month we’ll post what we judge to be the toughest questions that also ...
