Solid Core CT Series: Reliable Protection, Precise Measurement

Fault Detection

Current Precision

System Safety

High Accuracy Solid Busbar CT

Converts high AC current to a uniform secondary current for precise measurement by instruments, ensuring accuracy in monitoring and protection.

 

Cooperates with relay protection devices to detect faults promptly and isolate fault circuits, improving power system safety.

 

Measures primary currents from 200A to 6300A with secondary outputs of 5A, 1A, 0.1A, or 0.05A, and can collect low voltage overload and short-circuit signals for motor protection units.
