The PTSenR™ PTSPD31 is a wireless HFCT-based Partial Discharge (PD) Monitoring Sensor
designed for continuous online insulation assessment of HV and EHV power assets. Utilizing
advanced HFCT technology, it detects high-frequency PD signals through grounding conductors,
enabling early identification of insulation defects and supporting predictive maintenance.
Designed in accordance with recognized IEC partial discharge testing methodologies, the
PTSPD31 provides reliable asset condition monitoring to enhance system safety and reduce
unplanned outages. Its wireless architecture enables flexible deployment and real-time data
transmission without the need for extensive cabling.
The PTSPD31 is easy to install on existing assets and is ideal for monitoring power cables, cable
joints, terminations, transformers, GIS, and switchgear, helping utilities and industries improve
asset reliability, operational efficiency, and lifecycle management.
