Reliability in power distribution hinges on the early detection of insulation failure. Because localized field strength often triggers sparks within gas or solid dielectrics before a full breakdown occurs, monitoring partial discharge (PD) is the most effective way to prevent catastrophic asset loss.
Our latest handheld diagnostic tool integrates the industry’s most critical sensing technologies into a single, lightweight package designed specifically for field engineers.
Advanced Sensing Technologies
This partial discharge detector eliminates the need for multiple bulky instruments by combining four primary detection methods:
- TEV (Transient Earth Voltage): Perfect for routine switchgear checks, capturing pulses between 1–100MHz to identify internal defects.
- Ultrasonic Diagnostics (AA/AE): Features a 40kHz non-contact sensor for surface tracking and contact probes (20–300kHz) for oil-filled transformers or GIS.
- UHF (Ultra-High Frequency): Offers exceptional noise immunity in the 300–1500MHz range, making it the gold standard for complex GIS environments.
- HFCT (High-Frequency Current): Utilizes high-frequency current transformers to monitor grounding lines for cable joint and termination faults.
Precision Analysis in the Palm of Your Hand
Beyond simple detection, the unit provides deep analytical insights through several visualization modes:
- PRPD & PRPS Patterns: Phase-resolved snapshots that help technicians distinguish between real discharge and background interference.
- Time-Domain Waveforms: Displays the raw signal pulse to verify the nature of the discharge.
- Traffic Light Severity Indicator: Uses Green, Yellow, and Red color coding to provide instant feedback on the urgency of maintenance.
Rugged Design for Industrial Environments
Weighing less than 0.8kg, this device is engineered for portability without sacrificing performance. The 8000mAh battery supports over 8 hours of continuous field testing, ensuring you can complete a full substation sweep on a single charge. Data is easily exported via USB for automated report generation, streamlining your predictive maintenance workflow.
Ensuring the longevity of your grid starts with the right intelligence. By catching insulation degradation at the molecular level, you can transition from reactive repairs to a proactive, data-driven maintenance strategy.
