ETAC Service & Supply has introduced two new transformer designs for utility distribution and high-voltage substation applications. The company’s Dual-Voltage Padmount Transformers are engineered to ...

[Renaud] built a AC power meter from scratch. While commercial power meters like the Kill A Watt are available [Renaud’s] build gives an interesting insight into the methods used. At the heart of ...

People can thank voltage transformers, a kind of instrument transformer, for decreasing voltage intensity to safe levels and subsequently transporting the reduced power to homes. Transformers, which ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...
