Using Single-Phase Transformers to Create 3-Phase Systems

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 ...

Using a power transformer at a frequency it wasn’t designed for

Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

Do you use low-side current sensing?

Sensing of current going to a load is a critical and often mandatory requirement in many designs. While there are many contact and non-contact ways to accomplish this sensing, such as using ...
