What is a Current transformer?

A Current Transformer (CT) is a type of transformer used to measure electric currents, primarily in high-voltage circuits. It works by stepping down the current flowing through the primary winding to a proportional current in the secondary winding. The primary side carries the high current, while the secondary side connects to measuring instruments or protection devices, usually with a lower current (typically in the range of a few amperes). This allows for safe and accurate measurement of high-voltage currents. CTs are widely used in power plants, substations, and industrial equipment as an essential part of protection and measurement systems.

Application of Current transformer

✅Current Monitoring in Power Plants
In power plants, current transformers (CTs) are used to safely measure high-voltage currents, ensuring proper system monitoring.
✅Protection Systems in Substations
In substations, CTs help monitor electrical current and protect the system by triggering safety mechanisms if abnormal conditions occur.
✅Calibration of Power Measurement Devices
CTs are used in the calibration of power measurement devices, ensuring accurate current readings for efficient energy management.
✅Energy Consumption Monitoring
CTs are utilized in homes and factories to monitor energy usage, aiding in energy management and efficiency improvement.
