PDS100

The Doble PDS100 Partial Discharge Surveyor is a radio frequency interference (RFI) surveying tool that is designed for partial discharge measurement in a live substation.

Without the need for outages, the PDS100 can detect partial discharge (PD) in just a few seconds – making it an ideal tool for a condition based maintenance program.

Whole substations can be quickly surveyed and analyzed by simply walking around HV apparatus and using the PDS100 to detect and identify sources of PD and external interference.

    • Uses RFI technology to identify and locate defects
    • Detect harmful PD by the electromagnetic energy emitted from the area of activity
    • Compare reference baseline to readings from inside the substation
    • Spectrum and time modes
    • Store recordings in the instrument and later transfer to a PC for further analysis with PDViewer software
    • Rugged, light-weight, hand-held instrument
    • Works with a variety of sensors, probes and antennae for various applications

    • Safe and effective method for PD detection
    • Non-invasive inspection method for substation surveys
    • Use on a daily basis or during routine substation inspections together with other methods such as infrared scanning
    • Cost-effective way to include PD detection in your condition based maintenance program

    Telescopic Antenna

    • Antenna for wide range capture of UHF signals in open areas
    • Bandwidth 25-1900 MHz
    • Length: 310 mm (fully extended)
      • Standard accessory for PDS100
    • Fixed-length antenna for wide range capture of UHF signals in open areas
    • Bandwidth 25-1900 MHz
    • Length: 410 mm
    • Standard accessory for PDS100

    UHF spacer sensor

    • Connect a Doble UHF antenna directly to the antenna input of the PDS100
    • Place the sensor across a joint on a GIS to find evidence of partial discharge inside
    • See and correlate the pulse patterns in time domain mode

    TEV probe

    • Find PD in metal-clad switchgear and internally in transformers
    • Connect the TEV probe directly on the antenna input of the PDS100
    • Move the sensor across a grounded metal surface to find the location of the strongest signal amplitude​

    UHF Drain Valve Sensor DN50/DN80

    • Use on HV transformers for decoupling of electromagnetic PD signals from inside of transformers
    • Sensor fits into DN 50 or DN 80 drain valves
    • Supports “Performance/ Sensitivity Check” where high frequency test pulses can be injected with further integrated electrodes
    • Grounded sensors (for low frequencies)
