A leakage transformer, also called a stray-field transformer, has a significantly higher leakage inductance than other transformers, sometimes increased by a magnetic bypass or shunt in its core between primary and secondary, which is sometimes adjustable with a set screw. This provides a transformer with an inherent current limitation due to ...

Transformers designed for below-grade installation can be designed for periodic submersion in water. [14] Distribution transformers may include an off-load tap changer, which slightly adjusts the ratio between primary and secondary voltage to bring the customer's voltage within the desired range on long or heavily loaded lines.

As early as the 1980s, American transformer manufacturers began consolidating, and the industry continued to contract after its boom years of the ’60s and ’70s when most of the electrical grid ...
An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids. [1] The magnetic core of this transformer is made with a ferromagnetic amorphous metal. The typical material is an alloy of iron with boron, silicon, and phosphorus in the form of thin (e.g. 25 μm) foils rapidly cooled from melt.
