Partial discharge (PD) occurs due to insulation defects in high-voltage equipment, generating detectable signals like light, sound, and vibrations. Monitoring these signals helps identify potential hazards and prevent further damage.
Wrindu's handheld PD detector uses TEV, AE, UHF, and HFCT methods to measure PD magnitude and display waveforms. It’s designed for testing various electrical equipment like GIS, switchgears, and transformers, and allows for storing and retrieving 2D/3D PD data.
The device assesses PD severity by measuring intensity (maximum value of discharge pulses) and frequency (number of pulses). It's portable, easy to use, and doesn't interfere with high-voltage equipment operation, enabling accurate fault diagnosis.
Product Features
1. Configurable with different sensors to realize PD detection for almost all types of high-voltage electrical equipment.
2. Provides multiple discharge patterns including time-domain wave forms, PRPD (Phase Resolved Partial Discharge), and PRPS (Phase Resolved Pulse Sequence) for analyzing different discharge types.
3. User-friendly human-machine interface (HMI) facilitates data management for different equipment.
4. Built-in AE sensor and TEV sensor, with external interfaces for dedicated sensors of transformers, GIS, overhead lines, cables, etc.
5. Adopts non-intrusive detection method, no power outage required during testing, no additional high-voltage source needed, more convenient to use than traditional pulsed PD detectors.
6. Test bandwidth range: 30kHz ~ 2.0GHz, suitable for various detection principles in different frequency bands.
