Megger 1006296 Permanent mini HFCT 20

The Megger HFCT 20 (1006 296) Permanent High Frequency Current Transformer (HFCT) Sensor, 20mm Inner Diameter, is designed for decoupling of partial discharge (PD) signals and can be used for multiple applications in MV, HV and EHV range. The HFCT sensor is attached around the cable / accessories earth connection, e.g. a cable earth screen.

The permanent HFCT sensor is ideal for those assets where per­manent monitoring is required or where getting outages are almost impossible. Having pre-installed HFCT sensors in this case will allow online PD monitoring without the need of an outage.
