HSENS-T Rugged and Robust design to measure partial discharges 
Rugged and Robust design to measure partial 
discharges in Power Transformers, 
Switchgears, Rotating Machines and Cables 
(and their accessories)
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.
