HSENS-H Partial Discharge Sensor Applications

Detailed Overview

Hsens-H is a High-Frequency Current Transformer sensor. It is a split core and an inductive type sensor that can be clamped around the earth (ground) shield to measure PD signals. Based on power cable termination condition, an HFCT sensor can also be clamped around cable insulation without earth shield or around the cable with earth shield looped back for PD measurements. For HFCT clamped around the cable insulation without earth shield or cable with earth shield looped back, a high current variant can be used for rated load current of cable.

The sensor is IP65 rated and features integrated transient overvoltage protection inside sensor. Transient protection will help in minimizing transients that can be expected during PD monitoring
