China Partial Discharge Tester Pd Tester

HZJF-126 digital partial discharge tester is a new generation of high performance digitizing instrument with new technology, which is a substitute product of traditional analog amplifier. Adopt dual channel embedded system, TFT touch screen, stable and reliable system, low failure rate.System integrated use of the computer technology, analog electronics technology, high-speed signal collection technology and the advanced digital signal processing and graphic display technology, automatically complete the measurement and analysis of partial discharge.
1. The partial discharge tester adopts windows series operating platforms, are free to choose the elliptical, straight line and sine wave display, according to the 2D and 3D graphics analysis method and spectrum window, Q - V - F 3 D properties window, can static for partial discharge pulse in a cycle of test voltage measurement, observation, analysis in detail.
2. digital window operation can be done, any phase open window, single, double window choose, elliptical 360 ° rotation, in order to avoid interference effect on the measurement.
3. Multi-channel measurement and digital differential technology can flexibly compose pulse polarity discrimination or balance measurement loop, effectively suppressing the interference pulse signal. Advanced spectrum analysis can effectively reduce background interference.
4. Multipath input channel, which can be used to test six partial signals of tested product by one time boost, can conveniently analysis the source of the signals.It can be used for frequency band selection, gain conversion, spectrum analysis and 2D and 3D graphics display.
5. The system can also print or save a single image and save the graph data for continuous time for analysis.
6. The various waveform analysis and recording methods provided make it easy for you to judge the nature of the discharge;automatically recording and processing of all kinds of test data can quickly generate the test report of graphic and text.Parameter Characteristic Channel 2 electrical signal interface, an external synchronous interfaceSampling Rate0.5M,1M,2.5M,5M,10M,20M optionalSampling Accuracy12bitBand Range60dB,40dB,20dB,0dB,-20dB five gearsFrequency Band Range20k-100kHz,80k-200kHz,40k-300kHzMeasurement Range Nonlinear Error5%Measurement Range0.1pC~100000pCSensitivity0.1pCTested Product Capacitance6pF~250µFTest Power Source Frequency50~400HzDisplay Display Screen7" TFT true color touch LCD screen Resolution800x480Storage Physical Storage256MB DDR2,RAMSD card Storagestandard configuration16G,can be updated to 32G,used to save test data and recordInterface RS232Used to synchronize transmission interface with PCUSBCan connect external mouse keyboard and mobile storage devicePower SourceAC 220VElectric Signal Interface2 channel BNC interface, use to signal inputSMA interfaceexternal synchronize interfaceSD card slotCan insert Max 32G SD cardInternet AccessExtensibleEarth Connection ButtonUse to external earth connectionGeneral Description CPUMain Frequency 533MHzSystemWINCE6.0Working Environment Temperature-20ºC~45ºCStorage Environment Temperature-20ºC~60ºCDimensionLxWxH:350mm x 245mm x 175mmWeight5.8kg
