Current Transformers
Current Transformers small

Bristol Instruments carries current transformers (CTs) models designed to operate with a fixed input current range that runs from 0.25 to 20 A up to 1,000 A loads— depending on model.

Hinged CTs: Mini hinged current transformer models are available in 20, 50, 100 and 200 A load models. Specified accuracy is <0.5% and output is 330 mV AC at or near full scale—depending on model.

Split Core CTs
Split Core CTs small

Split Core CTs: provide linear output voltage that is directly proportional to the input current. These transformers are safely and easily installed over existing electrical power lines without disconnecting lines or interrupting service.

These split core CTs are shunted and, therefore, safe compared to other commercially available CTs and produce 333mV at full scale. Cost-effective and easy to use, they are available in three window sizes and for 5A to 1,200A loads. Specified accuracy is 1%.%.
