A partial discharge (PD) test kit identifies early insulation defects in high-voltage equipment, including transformers, cables, and switchgear. By detecting tiny electrical discharges in picocoulombs (pC), it prevents system failures and extends equipment life. Wrindu’s PD kits from China deliver precise, IEC-compliant testing with multi-sensor integration, making them ideal for utilities, OEMs, and energy storage facilities worldwide.
What Is Partial Discharge Testing?
Partial discharge testing measures microscopic electrical discharges in insulation systems to detect faults before complete breakdown occurs. These early warnings help utilities and manufacturers maintain equipment reliability.
Wrindu produces advanced PD test kits featuring ultrasonic, TEV, and HFCT sensors for comprehensive monitoring. Portable designs enable field testing, while software provides phase-resolved analysis and data logging. OEM customization ensures kits meet specific voltage ratings and sensitivity requirements, complying with IEC 60270 standards.
| PD Detection Method | Sensitivity Range | Typical Applications |
|---|---|---|
| Ultrasonic | Surface PD | Switchgear, bushings |
| TEV | Internal PD | Cables, motors |
| HFCT | High-frequency | Transformers, GIS |
