HFCT Sensor
The HFCT Sensor (High Frequency Current Transformer) provides high-sensitivity partial discharge detection and can effectively measure the high-frequency pulse currents generated by Partial Discharge (PD) in high-voltage equipment. Its clamp-on structure installs quickly on grounding conductors — suitable for on-site inspections, long-term monitoring, and 24/7 Online Partial Discharge Monitoring.
HFCT SENSOR Features
- 01
High-sensitivity partial discharge pulse current detection
The HFCT Sensor (High Frequency Current Transformer) provides high-sensitivity partial discharge detection and can effectively measure high-frequency pulse current signals generated by Partial Discharge (PD) in high-voltage equipment.
- 02
Clamp-on design for fast installation on grounding conductors
This product uses a clamp-on structure and can be quickly installed on high-voltage equipment grounding conductors without major changes to the existing equipment configuration. It is suitable for on-site inspections, long-term monitoring, and 24/7 Online Partial Discharge Monitoring.
- 03
Wide frequency range for better partial discharge identification
The HFCT Sensor has a wide operating frequency range, allowing it to capture PD waveform characteristics and high-frequency signal changes more completely. This helps improve PD Detection accuracy and strengthens identification of PD types, insulation abnormality analysis, and equipment health diagnostics.
- 04
Large aperture design for various high-voltage equipment
The sensor inner diameter is greater than 40 mm, making it suitable for grounding conductors on various high-voltage equipment.
- 05
Nanosecond-level high-speed pulse response
The HFCT Sensor provides nanosecond-level response to partial discharge pulses, allowing real-time capture of fast-changing PD pulse signals and improving the timeliness and reliability of the partial discharge monitoring system.
