Pictures for reference only.
The GDPD-414H handheld Partial Discharge Detector adopts smart quick intelligent power test system (Soft No. 1010215, trademark registration number 14684481). It can flexibly configure various sensors according to different products to be tested. TEV, ultrasonic and HFCT are suitable for partial discharge detection of high-voltage switchgear and ring network cabinet; Ultrasonic and UHF are suitable for detecting GIS; Ultrasonic and HFCT are suitable for testing power 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
● Portable ABS engineering chassis. All PD detection hosts, tablets, sensors, chargers and signal cables are placed in the portable engineering chassis. The total weight is less than 5KG, easy for carrying and operating.
● High-speed sampling board, 4-channel synchronous data acquisition, signal processing, feature parameter extraction, data can be sent to the handheld terminal by wire and wireless.
● Analyze software based on ARM embedded system. Display software based on windows system.
● A data acquisition host can simultaneously configure 2 or 4 channels (selected by buyer) of the same or different sensors and simultaneously collect and analyze 2 or 4 channels of signals.
● 8.1inch 1280 x 800 IPS touch screen.
● The software system judges the discharge energy and location according to the detection data, and it can display the PRPS and PRPD maps, ellipse diagrams, discharge rate maps, QT maps, NT maps, PRPD cumulative maps-ϕ-Q-N maps of each signal channel, and can display amplitude and pulse number of each signal channel. All the data can be stored.
● Over-limit alarm. Using three-color indication modes of red, yellow and blue, which indicates the severity of partial discharge and facilitates information reading.
