Discover different types of transformers & their applications, including liquid-filled, dry-type, padmount, substation, polemount, and submersible transformers.

Overview of the common tests performed on transformers, including Winding Resistance, Megger, Transformer Turns Ratio, Load-Loss, Leak Tests, and others.

A loop feed transformer can accommodate both radial and loop distribution systems, whereas radial feed transformers almost always appear in radial systems.

When choosing a general purpose low voltage dry type transformer (below 600v), you'll need to consider phase type, kVA rating, and input and output voltage.

Harmonics can be harmful for a transformer's operation. However, they can be mitigated by K-Factor rated transformers, Zigzag transformers, and other options.
