Hsens-T is a Transient Earth Voltage Sensor 
that  can be used to detect internal, 
external and surface  partial discharges 
inside metal clad switchgear or  power 
cables termination box of rotating machines
and power transformers. An application of HFCT along with TEV can help in PD 
diagnostic and  confirmation of internal versus external PD. Sensor is IP65 rated with 
integrated transient overvoltage  protection feature inside sensor.
Transient protection will help in minimizing transients that can be expected during PD 
monitoring. TEV  sensor has strong magnets that help it to attach to the walls of metal 
clad switchgear. TEV forms a  capacitive coupling with grounded metal switchgear to 
detect transients of external PD happening  inside metal clad switchgear at termination.
