What are the energy storage devices for dry-type transformers

What is a dry type transformer?

A dry type transformer is cooled by normal air ventilation instead of a liquid such as mineral oil or Envirotemp FR3. These transformers are also known as air-cooled transformers.

Are dry type transformers better than liquid cooled transformers?

Due to advancements in design, materials, and manufacturing methods over the past three decades, dry type transformers have significant advantages over liquid-cooled transformers in many commercial and industrial applications, especially in the medium voltage range (2.5KV – 34.5 KV).

What is the typical warranty duration for a dry type transformer?

Comparatively, a traditional warranty for a dry type transformer is just one year. At ELSCO, we attain a high level of reliability and provide extended warranties.

Where should dry type transformers not be installed?

Dry Type transformers are not recommended for indoor installations or anywhere a fire could have catastrophic results. They are cooled by clean ambient or forced air and contain no liquids, presenting a minimal fire hazard.

Are dry type transformers safe?

Dry Type transformers, which are cooled by clean ambient or forced air and contain no liquids, present a minimal fire hazard and are suitable for indoor installations or anywhere fire hazards must be avoided. They are not recommended for indoor installations or anywhere a fire could have catastrophic results.

How should a dry-type transformer be protected against moisture?

If a dry-type transformer is to be moved outdoors during inclement weather, it should be thoroughly protected against moisture. Storage areas should be as clean and dry as possible without extreme temperature variations. Protective wrappings should be left intact until the transformer is moved to its permanent location.
