Common Causes of Failures of Power Transformers
As with most of electrical equipment, the key causes of failure of power transformers are either due to electrical failure or mechanical failure. These failures don’t occur that often as compared with other failures in other electrical equipment like switchgear. Common failures of power transformers and their causes are discussed in the following sections. Typical…

Testing Power and Distribution Transformers
The typical practice for testing power and distribution transformers is to carry out a comprehensive set of tests at the manufacturer’s works. The number and nature of the tests depend on whether the transformer is the first of a new design or not, additionally a few relatively simple tests are done after installation at site…

What is the difference between a Power transformer and a Distribution Transformer?
Introduction The transformer, in simple terms can be defined as the voltage regulator. It helps in stepping up and stepping down of the voltages. We all have seen transformers in our locality, where the current is passed from higher voltage to the lower voltages. In this blog, we will discuss about the differences between the…

Ideal Transformers
A transformer consists of several coils wound on a common core that usually consists of laminated iron (to reduce eddy-current loss). Transformers are usually used to adjust the values of ac voltages. A transformer can step up or step down voltage. Transformers are used in electric power distribution. To transport power over long distance, large…
