Current transformer is a crucial measuring and protective device in the power system. Its core function is to proportionally convert large currents into standard small currents for safe and accurate measurement and monitoring.
Applications:
Measurement: Provide input signals proportional to the primary current for ammeters, energy meters, power meters, power factor meters, etc.
Protection: Provide a signal reflecting the fault current of the primary system to the relay protection device.
Monitoring and Control: Provide current information in SCADA systems and automation devices.
Features:
Current conversion: Convert high current into standard low current.
Electrical isolation: Through magnetic coupling between the primary side (high voltage, high current) and the secondary side (low voltage, low current), electrical isolation between high and low voltage, strong and weak current is achieved, greatly ensuring the safety of operators and instrument equipment.
Standardized output: The rated current on the secondary side is usually 1A or 5A, which allows for standardized design of measuring instruments and protective relays connected to it.
High precision: CT used for measurement usually has a high level of accuracy to ensure measurement accuracy.
Overcurrent capability: The CT used for protection needs to be able to withstand very large overcurrent without saturation during faults to ensure reliable operation of the protection device.
