Frequently asked questions (FAQ)

Q: What is the most common failure of transformers?

A: During operation, the transformer's electrical windings and core are subjected to a variety of forces, such as expansion and contraction due to thermal cycling, vibration, localised heating due to magnetic flux, inrush forces due to fault currents, and overheating due to overloading or insufficient cooling. These forces gradually degrade the electrical insulation of the windings and may eventually lead to transformer failure.

Q: What is dry type power transformer?

A: Unlike liquid-filled transformers, dry-type transformers do not use liquid to dissipate excess heat and meet temperature classification requirements. Instead, the coils inside a dry-type transformer consist of a gaseous or dry insulating medium.

Q: How do I choose a dry type transformer?

A: In summary, selecting the right dry-type transformer requires consideration of several factors, including power rating, voltage level, frequency, ambient conditions, noise level, efficiency, size, and weight.

Q: What is the winding of a dry type transformer?

A: Transformer windings are the coiled components within a transformer that facilitate the absorption and distribution of electrical power throughout the device. In dry-type transformers, there are typically two distinct windings: one responsible for absorbing power from the source and another dedicated to transferring that power to the load. Both copper and aluminum windings serve this fundamental function effectively.
