Sensor is IP65 rated and integrated 
features  of transient overvoltage protection 
inside  sensor. Transient protection will 
help in  minimizing transients that can be 
expected  during PD monitoring.
Ruged Monitoring’s High Frequency Current Transformer sensor HSENS-H 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 to measure PD. For  HFCT clamped around the cable insulation 
without earth shield or cable with earth shield looped  back, high current variant can 
be used for rated load current of cable.
