How to do the transformer testing and what are the different types of transformer testing?

By testing a transformer we can confirm the performance and specification of a transformer. Some of the transformer testings will be done by the manufacturer and they are type tests and routine tests of the transformer. Certain types of tests will be carried out by the consumer to determine the ability and quality of the …

How to do Megger test/insulation resistance for transformer?

Transformers are one of the costliest equipment used in distribution and transmission process of power. The transformer has to go through different testing procedures periodically to prove that the transformer works properly. Deterioration of the transformer insulation resistance is one of the most common causes of failure of the transformer: a failed transformer is a costly replacement …

Why transformer testing is needed and how to do the maintenance of a transformer

What is the transformer A transformer is a device that can transfer electrical energy from one circuit to another through an inductively coupled conductor which is the transformer’s coils. A varying magnetic flux will be created in the transformer’s core by the varying current in the primary winding and thus a varying magnetic field through …
