Portable PD Detector & Partial Discharge Tester / Non-Invasive Power Equipment Insulation Testing Tool with TEV Sensor for Live Detection & Diagnosis
Partial Discharge Detector | Comprehensive Insulation Diagnostic Expert for Power Equipment
Product Overview
The Partial Discharge Detector is an intelligent diagnostic tool designed for power systems. It enables rapid detection of insulation defects in high-voltage switchgear, ring main units, transformers (including dry-type transformers), GIS, overhead lines, cables, and more. Equipped with high-precision sensors and multi-dimensional analysis technology, it quantifies partial discharge intensity and frequency in real time, providing critical data for equipment health assessment, preventive maintenance, and early fault warning.
Key Features
✅ Full-Scenario Compatibility
· Supports TEV, AE (contact/non-contact ultrasonic), UHF, and HFCT sensors, covering nearly all high-voltage electrical equipment, including transformers, GIS, cables, and switchgear.
✅ Multi-Dimensional Discharge Analysis
· Generates time-domain waveforms, PRPD (Phase-Resolved Partial Discharge), and PRPS (Phase-Resolved Pulse Sequence) diagrams to accurately identify corona, surface discharge, floating discharge, and other fault types, enhancing diagnostic reliability.
✅ Non-Invasive & Efficient Detection
· No power outage required! No external high-voltage source! Directly captures discharge signals through sensors, significantly reducing downtime and operational costs.
✅ Wide Bandwidth & High Sensitivity
· Detection frequency range: 30kHz–3.0GHz. Supports UHF, HFCT, and other principles with sensitivity as low as ≤50pC, capable of detecting weak discharge signals.
✅ User-Friendly Interface
· Features a 7-inch touchscreen with intuitive controls for data storage, historical comparison, and report generation, ideal for on-site analysis and long-term monitoring.
