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 testedobjects. TEV, AEand HFCT are suitable for partial discharge detection of high-voltage switchgear and ring network cabinet; AEand UHFaresuitable for detecting the insulation state of GIS; AEand HFCT are suitable for testingthe 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.FeaturesThe whole machine adopts portable ABS engineering chassis. PD detection host, tablet/notebook, sensors, charger and signal cables are placed in the portable engineering chassis. The total weight is less than 8KG, easy for carrying and operating.Adopt self-developed high-speedDSP/FPGAsampling 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 optionalThe 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, ϕ-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.Averagetrouble free time: over 50000hours.Safety performance: meetsGB/T 19862-2005 general requirements for switchgear monitoring equipment.Electromagnetic compatibility:Electrostatic discharge immunity meets level IEC 61000-4-2: 2001Damped oscillatory magnetic field immunity meets IEC 61000-4-10: 1993level 3Power frequency magnetic field immunity meets IEC 61000-4-8: 2001level 3Pulse magnetic field immunity meets IEC 61000-4-9: 1993Level 3Power supply: powered by 12V lithium battery, power consumption < 20W, sustainable workfor more than 6hours.Environmental conditions:Storage temperature: -40ºC~ +85ºC,Working temperature: -20ºC~ +60ºC,Relative humidity: 5% ~95% without condensation at 35ºCLightweight and easy to carry, it is suitable for field useSignal acquisition host weight <3kgSpecificationsPD signal acquisition host:CPU Working frequency1.2GHzOperating systemLinx embedded operating systemWired network portLAN network portWireless network portBuilt-in WiFiSystem running memory1GSystem storage memory512MData acquisition frequency250MHzUltrasonic detection channel:Measurement range0-60mVFrequency detection range20~200kHzUHF detection channel:Detection frequency300~1800MHzMeasurement range-80~10dBmError±1dBmResolution1dBmHFCT detection channelFrequency range0.5~100MHzError±1dBDynamic Range60dBMeasurement range0-100mVAccuracy1dBTEV detection channelFrequency range3~100MHzMeasurement range0-60dB/mVSensitivity0.01mVError±1dB/mVResolution1dBm/mVBatteryBuilt-in batteryLithium battery, 12V, 4000mAhUse timeabout 8 hoursCharging timeabout 2 hoursBattery protectionOver-voltage and over-current protectionBattery chargerRated voltage 12.6VCharging output current2AOperating temperature-20ºC-60ºCOperating humidity<80%Handheld display terminal (industrial grade)or ThinkPad notebook:CPUIntel Quad Core Atom Z3735FGPUIntel HD Graphic (Gen7)Flash32GBRAM2GBOperating systemWindows10Display8.1 inch 1280×800 IPS screenNetwork interfaceWifi and BluetoothBattery 3.7V 8500mAH polymer lithium ion batterySizePD acquisition host size395mm*295mm*105mmPDacquisition host weight0.85kgDisplay tablet size570mm*360mm*240mmDisplay tablet weight0.85kgOverall box size570mm*360mm*240mmWorking environmentWorking temperature-20ºC~50ºCEnvironment humidity0~90%RHIP level54
