How Does Temperature Influence the Lifespan of a Transformer?

Posted by Bill Dull | December 18, 2021 | 0 Comments

All electrical devices produce heat as an operational byproduct. In transformers, normal operation causes an internal temperature increase or temperature rise. When the transformer is at its nameplate rating, the transformer temperature rise is the average temperature increase of the windings above the ambient temperature. This increase in temperature has the potential to shorten the [...]

Making Sense of Current Transformers

Posted by Bill Dull | April 26, 2021 | 0 Comments

Current transformers (CTs)—also known as current sense transformers or current sensors—are instruments that are designed and manufactured to detect electrical currents and convert them into more usable forms for different applications. They perform these detections and conversions by measuring the larger current value in the primary winding and developing a corresponding smaller current in the [...]
