Product Description

UHF and AE method is acknowledged and suitable technology to be used in online partial discharge detection. 

GDPD-300UF uses ultrasonic detection technology (AE), which can effectively 

ensure signal sensitivity in the interference on-site environment .

It is suitable to detect PD flaw and locate PD signal for power cable terminals, instrument transformers etc.

Features

• Non-invasive detection methods, with ultrasonic signal detection.
• Ultra-high frequency sensor has functions of directional reception. During testing, when it closes the location where is easy to radiate UHF electromagnetic signals, it can detect PD signals.
• Ultrasonic sensors can detect PD signals on grounded metal shell of electrical equipment. It is more sensitive to vibration signal caused by point burr discharge and suspended particles, and is able to locate discharge source.
• Hand-held design, Lithium battery supply with 8 hours endurance.
• Large capacity memory to meet the needs of the site inspection.

Application

• PD detection of Transformers
• PD detection of Switch cabinet
• PD detection of Power cable
• PD detection of Insulators on the line
• PD detection of Insulators on the railway
• PD detection of GIS
• Air impermeability detection of SF6 gas
