High Frequency CT Series: Precise Signals, Non-Invasive Design

Fast Installation

High Accuracy

Full Range

Precision High Frequency Sensor

Detects high-frequency current signals generated by partial discharge inside cables through the grounding wire for accurate local discharge monitoring. 

 

Uses a Rogowski coil working principle with no direct electrical connection between the sensor and the measured circuit.

 

Supports non-invasive online detection without interrupting equipment operation, improving inspection efficiency and safety.
