High Frequency Current Transformers

Partial Discharge High Frequency Current Transformer - ø17mm

General Description

The HFT-0017 Partial Discharge High Frequency Current Transformer is idealy suited for Partial Discharge measurements especially when used in combination with surge capacitors for online partial Discharge measurements/monitoring. The use of the HFT-0017 allows to use the surge capacitor (which is used for the protection of the machine winding) as a partial discharge coupling capacitor. The HFT-0017 offers a standard BNC female connector for an easy connection together with standard coaxial cables as RG58. A suitable mounting bracked is supplied with the HFT-0017 which allows an easy mounting in most of the installation locations.
