PD detector

The PD detector is mainly used for power transformer, HV CT/PT, arrester, HV switch, HV XLPE cables, etc. The partial discharge test is used to judge the qualification of power products, which needs to be used in conjunction with the AC withstand voltag

  • JFD-Digital PD detector

    The PD test is the main test items for electric equipments insulation, and the partial discharge is the important parameter of electric equipments quality. The detector is based on modularization, designing the simulation parts as standard module according to different function. The modules can be added or deleted as per users requirement. The module is standard Europe type, which is convenient for maintenance and update. It adopts advanced hardware process system, and NI card from America National Instrument. It also adopts digital filtering and other signal process device to collect and analyze the PD signal.

    Technical parameter

    The test is based on apparent charge measuring description as per IEC 270. The calibrated charge is generated from input impulse of 100pF capacitor. 10mV step voltage means 1pC partial discharge and the rising time of step voltage is less than 50ns.

    Test Frequency range: 50/60Hz(30Hz ~ 1kHz optional )
    Power supply: 220V/50Hz
    Test sensibility: <0.02pC( load capacitor 50pF)
    Minimum measuring apparent charge: <0.1pC
    Sampling depth of each channel: 32M
    Linearity: <±1%
    Max sampling rate: 50MHz( can up to 100MHz) •
    Synchronization mode: Inner trigger/outer trigger/manual
    Adjustable input attenuation: <10μS Max input pulse voltage 100V
    Time window: 0 ~ 360°,more time windows can be set
    Adjustable input attenuation: 0 ~ 96dB,band 4dB
    Frequency bandwidth: 5kHz~1MHz
    Using computer to measure, control, display, save and analyze;
    The fault locator optional.
