Current transformers (CTs) are essential instrument transformers widely used in power systems for current measurement, energy metering, and relay protection. A complete set of standards defines their design, manufacturing, testing, accuracy classes, safety requirements and operating limits to guarantee consistent performance and interoperability across different manufacturers and regions.
As a professional manufacturer of current transformers, we are delighted to introduce our capability to supply qualified current transformer products for ABB’s power distribution, renewable energy and industrial automation projects. With long-term experience in electromagnetic design, precision winding and epoxy encapsulation, we fully understand the stringent quality, accuracy and reliability requirements for every unit, and we are ready to deliver customised, standard-compliant solutions matching ABB’s technical specifications.
Current transformer (CT) saturation is a critical electromagnetic issue that impacts the accuracy and reliability of power system measurement, protection and monitoring. Under regular working conditions, the CT core operates in its linear magnetic region. Magnetic flux varies proportionally with the primary current, allowing the device to step down large primary AC current into a standard small secondary current for meters, transducers and protective relays.
Current transformers and potential transformers are two core types of instrument transformers used in power distribution and transmission systems. Both devices operate on the principle of electromagnetic induction and are mainly used to convert high power system parameters into standard low‑level signals for measurement, monitoring and system protection. They also provide electrical isolation between high voltage primary circuits and low voltage secondary control equipment to ensure operational safety.
