Transformers quietly handle one of the most important jobs in the power grid—changing voltage levels so electricity can travel safely. This video explains how coils and magnetic fields work together ...

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 ...

It is important for machine design engineers to understand how transformers work so they can design machinery that operates optimally within the proper voltage ranges, as well as select the right ...

Have you ever noticed those metal canisters attached to utility poles? Those are transformers. They convert high-voltage electricity from power plants to lower-level electricity that’s safe for homes ...

Power transformers are often the main source of common-mode noise in isolated switching power converters. Why? Because inside the transformer, the windings on the primary and secondary sides of the ...

The U.S. Department of Energy’s (DOE) Office of Electricity (OE) has released a report for distribution transformers in the electrical power grid. The report, prepared by researchers at the National ...

The United States is currently experiencing unprecedented imbalance between supply and demand for transformers—not the shape-shifting robots, but the crucial devices used on the power grid. Almost ...

The iron-core transformer is the 140-year-old technology that props up both the electrical grid and AI companies. The devices are clunky but reliable, which explains why they’re still in use: If it ...
