Application of Current Transformers

Current transformers (CTs) are essential components in electrical power systems, primarily used to measure and monitor electrical currents. They step down high currents to lower, safer levels that can be measured by instruments like ammeters, wattmeter, and protective relays.

Measurement and Monitoring

Energy Metering

Protection Systems

Substation & Power distribution networks

Key Benefits of Current Transformer

Used to monitor high-voltage lines

CTs are used worldwide to monitor high-voltage lines across national power grids

Low insertion impedance

CTs minimize the impact on the primary circuit and maintain system efficiency.

Wide dynamic range

CTs can measure both high and low currents with high accuracy

Can handle high fault currents

CTs can handle high fault currents and transient conditions without damage.
