Typical maintenance of transformers includes periodic testing of the nitrogen blanket for flammable vapors to evaluate the health of the transformer. If the testing reveals a buildup of flammable vapors, the transformer can be removed from service in a planned manner instead of a catastrophic manner (such as an explosion). (read more)

The magnetic flux in a typical A.C. transformer core alternates between positive and negative values. The magnetic flux in the typical pulse transformer does not. The typical pulse transformer operates in an "unipolar" mode (flux density may meet but does not cross zero). (read more)

Hevi-Duty offers the following family of transformers that meet the strict efficiency standards required by the Energy Policy Act of 2005. The efficiencies of these transformers are optimized for the load losses calculated at 35% of the name plate rating. This 35% represents an industry average load of most LVGP transformers.

What is the purpose of a current transformer? It measures alternating current flowing through a conductor. Since it is used to measure current, a current transformer is often classified as a type of instrument transformer. One could measure the voltage drop across a known resistor. This is okay for low current applications but is often impractical for high current applications. (read more)
