Description

The HFT-0017 and HFT-0024  Partial Discharge High Frequency Current Transformers are ideally suited for Partial Discharge measurements especially when used in combination with surge capacitors for online partial Discharge measurements/monitoring.

The HFT-0017 and HFT-0024 uses the surge capacitor (which is used for the protection of the machine winding) as a partial discharge coupling capacitor. The HFT-0017 and HFT-0024 offer a standard BNC female connector for an easy connection, together with standard coaxial cables as RG58. A suitable mounting bracket is supplied which allows an easy mounting in most of the installation locations.

Both versions are fully compliant with the IEC-60270 and IEC-60034 standard and are ATEX certified.
