HFCT
High frequency current transformer sensor for PD detection on active cables and electrical assets.
Detects high frequency pulses generated by partial discharge activity
Installs around earth connections to enable non-intrusive testing
Supports regular condition monitoring without disrupting operations
The High Frequency Current Transformer (HFCT) is a sensor used to detect partial discharge activity on medium and high voltage electrical assets, including power cables and terminations. Installed around the earth connection of shielded cables or equipment, it captures high frequency pulses associated with insulation defects while rejecting normal power frequency currents.
Suitable for both portable testing and permanent monitoring, the HFCT can be used with the UltraTEV Plusยฒ for on-site surveys or integrated into the Astute HV Monitoring system for continuous measurement. It enables safe, non-intrusive detection of partial discharge on live assets, supporting routine condition monitoring and early identification of developing faults. The HFCT is available in two variants, F50 and F100, offering different aperture sizes to suit a range of cable sizes and installation requirements.
Sensitive partial discharge detection
Captures high frequency pulses associated with partial discharge, enabling reliable identification of insulation defects.
Non-intrusive installation
Fits around earth straps on shielded cables and equipment, allowing testing without disconnecting or disturbing assets.
Rejects power frequency noise
Designed to filter out normal system currents, focusing on the high frequency signals linked to partial discharge activity.
