Product Description

General Information

GDPD-414 Portable Partial Discharge Analyzer adopts smart quick intelligent power test system (Soft No. 1010215, trademark registration number 14684481). HVHIPOT company introduces international advanced PD detection technology to develop and produce portable and efficient PD inspection tools for live high-voltage insulation equipment. It can flexibly configure various sensors according to different tested objects. TEV, AE and HFCT are suitable for partial discharge detection of high-voltage switchgear and ring network cabinet; AE and UHF are suitable for detecting the insulation state of GIS; AE and HFCT are suitable for testing the insulation state of the cable. The built-in expert diagnosis system can analyze the test data and judge the discharge energy and possible parts. It is widely used in electric power and railway. 

 

 

Features

• Adopt self-developed high-speed DSP/FPGA sampling board, 4-channel synchronous data acquisition, signal processing, feature parameter extraction, data can be sent to the terminal by wire and wireless. 
• Software system: analysis software based on ARM embedded system, display software based on windows system. 
• A data acquisition host can simultaneously configure 4 channels of the same or different sensors, and can simultaneously collect and analyze 4 channels of signals. 
• 6/8/16 channels can be configured according to customer's different demands. 
• 8.1 inch tablet or Thinkpad notebook as optional 
• The software system judges the discharge energy and location according to the detection data, and can display the PRPS and PRPD maps, ellipse diagrams, discharge rate maps, QT maps, NT maps, PRPD cumulative maps, fai-Q-N maps of each signal channel, and can display PD signal amplitude and pulse number of each signal channel .  
• Over-limit alarm: the software adopts three-color indication modes of red, yellow and blue, which indicates the severity of partial discharge and facilitates information reading. 
• Average trouble free time: over 50000hours. 
• Electromagnetic compatibility: 

Electrostatic discharge immunity meets level IEC 61000-4-2: 2001

Damped oscillatory magnetic field immunity meets IEC 61000-4-10: 1993 level 3

Power frequency magnetic field immunity meets IEC 61000-4-8: 2001 level 3
