product
  • 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
