Product Description

The PDS3 partial discharge sensor integrates ultrasonic, TEV (Transient Earth Voltage) and UHF (Ultra High Frequency) technologies to detect partial discharges in middle-high voltage equipment. PDS3 can monitoring of transformers, high-voltage switchgear, and cable joints. PDS3 is highly portable, offers fast measurement speeds, and boasts strong anti-interference capabilities, making it suitable for various field applications.

1. Rugged, compact design;
2. Non-intrusive detection method;
3. Strong magnets to attach sensor;
4. Rapid detection of partial discharge conditions;
5. Easy to Install, integrated transient (Over-voltage) protection;
6. Suitable for extreme environment, outdoor substation;
7. Measures PD in high-frequency UHF range;
8. Ensures sensitive PD measurements in noisy environments;
9. Designed specifically for PD detection at HV cable terminations;
10. RS485, Modbus-RTU, SCADA systems.
