The VEC-PD100P is a portable partial discharge (PD) testing instrument designed to detect UHF and ultrasonic signals generated by partial discharge in the insulation of high-voltage equipment. It supports acoustic-electrical combined PD location to accurately analyze the insulation condition of HV assets.
Compact, lightweight, user-friendly and powerful, the VEC-PD100P enables efficient on-site testing, automatic diagnosis and precise localization of insulation defects.
It is widely applied to various high-voltage equipment including GIS, transformers, switch gears, generators and other HV assets.
FAQ
Q1: What is a portable partial discharge detection and location device?
A: This is a specialised instrument that can be rapidly deployed on-site to detect partial discharges within high-voltage equipment—such as transformers, GIS and switchgear—whilst power supply remains uninterrupted, and to precisely locate the source of the discharge. This helps prevent sudden failures and informs maintenance decisions.
Q2: What detection methods does it employ?
A: It primarily utilises combined Ultra-High Frequency (UHF) and Acoustic Emission (AE) detection technologies. This enables the localisation of discharge sources and is suitable for complex structures such as transformer oil tanks, GIS gas compartments and cable joints.
Q3: Is on-site operation complicated?
A: No, it is not. The instrument uses a laptop or tablet as the human-machine interface terminal; the interface is intuitive and operation is guided by a wizard. Furthermore, the instrument is designed to be lightweight and portable, allowing a single operator to carry it and perform tasks.
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.
