Ensuring the reliability of high-voltage infrastructure requires advanced, portable, and versatile diagnostic tools. Our latest Handheld Partial Discharge (PD) Detector is a multi-functional powerhouse designed to monitor and evaluate the insulation health of critical assets, including switchgear, GIS, transformers, and power cables.
Advanced Quad-Method Detection Technology
The system leverages four primary detection methodologies to ensure no discharge event goes unnoticed:
- Transient Earth Voltage (TEV): Utilizing an integrated sensor to capture transient voltage signals on the equipment casing.
- Ultrasonic (AE/AA): Supports both non-contact sensors for overhead lines and contact-based sensors for oil-filled or gas-insulated equipment.
- High-Frequency Current (HFCT): Specifically engineered for detecting PD pulses in power cable grounding systems.
- Ultra-High Frequency (UHF): Provides high-sensitivity electromagnetic detection for complex GIS and transformer environments.
Integrated and Modular Sensor Design
The detector is engineered for maximum efficiency, featuring a lightweight, ergonomic handheld design.
Built-in Capabilities
The core unit includes internal sensors for immediate deployment:
- Integrated TEV Sensor: Located at the rear for collecting transient earth voltage signals.
- Internal AA Ultrasonic Sensor: Designed for rapid capture of airborne acoustic signals.
External Expansion Interfaces
For specialized testing, the device features dual top-mounted interfaces:
- Interface A: Dedicated to external HFCT and UHF high-frequency signal inputs.
- Interface B: Supports a range of specialized ultrasonic probes, including Extended AA, Parabolic AA, and Contact AE sensors.
Field-Ready Engineering
Designed for the rigors of field use, the system includes a high-definition display and several utility ports located at the base:
- USB Port: Facilitates both rapid device charging and seamless data transfer to a PC for further analysis.
- Headphone Jack: Enables real-time audio monitoring of non-contact ultrasonic signals, allowing technicians to “hear” the discharge.
Flexible Configurations for Every Application
To meet diverse operational needs, we offer multiple configuration packages. While the XXXX-Q model provides a full suite of all sensors (AA-Y, AA-J, AE, HFCT, and UHF), other versions like the XXXX-P focus on ultrasonic detection, and the XXXX-L is optimized for cable testing.
By integrating high detection efficiency with a compact, easy-to-use form factor, this detector is the essential tool for modern predictive maintenance in power systems.
