Widely employed in power utilities, railway systems, industrial electrical maintenance, and high-voltage equipment monitoring, the VEC-PD600H delivers reliable, high-precision partial discharge detection for critical power assets.

FAQ

Q1: What is a handheld partial discharge detector?

A: This is a portable instrument specifically designed for rapid on-site inspections, used to detect partial discharge defects in high-voltage equipment such as switchgear, distribution cabinets, cable terminations and GIS whilst the equipment is live. It supports multiple detection modes, including Ultra-High Frequency (UHF), Transient Earth Voltage (TEV), Acoustic Emission (AE/AA) and High-Frequency Current (HFCT), helping operations and maintenance personnel to quickly assess the insulation condition of the equipment.

Q2: What detection methods does it employ? What scenarios are they suitable for?

A: The instrument integrates five mainstream detection technologies: 1) Acoustic Emission (AE/AA): Suitable for partial discharge detection in switchgear and GIS equipment; 2) Transient Earth Voltage (TEV): Suitable for detecting partial discharges inside switchgear; 3) Ultra-High Frequency (UHF): Suitable for detecting discharges inside GIS and switchgear; 4) High-frequency current (HFCT): Suitable for partial discharge detection in cables and joints.

Q3: Is it easy for field engineers to operate?

A: It is very user-friendly. It features simple operation, the ability to connect to a mobile phone or laptop for display, a lightweight handheld design, and requires no specialist training.

Q4: What are the typical application scenarios?

A: It is widely used in substations, industrial plants, and the petrochemical, metallurgical and mining industries for routine inspections, preventive maintenance and fault diagnosis.

Q5: Does it support data storage and export?

A: It supports real-time data logging, historical data storage and waveform display; test data can be exported for further analysis and report generation.
