Read MoreIndicators That Dry Type Transformers Are Failing
Transformers should be built to last, and dry type transformers, in particular, avoid some maintenance issues that can occur with oil-filled transformers. However, some potential problems can still cause a transformer to fail. In this post, we’ll discuss these problems and explain how to tell if your dry type will stop working soon so you […]
Read MoreCopper vs. Aluminum Dry Type Transformer Windings
Dry type transformers typically feature either copper or aluminum windings, also known as coils. Transformer windings refer to the coils within the transformer that draw and distribute power inside the unit. There are typically two windings in a dry type transformer — one that draws power from the source and another that transfers that power […]
Read MoreWhy Is My Dry Type Transformer Making a Loud Humming Noise?
A transformer may hum or buzz without signaling that it is malfunctioning. Many dry type transformers produce steady humming noises when magnetized and operating normally. However, if you hear a loud hum or a buzz that’s not usually present, it could signal an issue. 4 Reasons Dry Type Transformers Make Loud Humming Noises If you […]
Read MoreWhy Is Your Dry Type Transformer Overheating?
Since transformers convert high voltages into consumable power, they generate significant heat. This heat can significantly affect the transformer’s efficiency and will shorten its life span. With energy efficiency becoming a top priority in many of today’s power applications, choosing a dry type unit that can adequately meet the required power needs and subsequent thermal […]
