PD-SG1 'Standard' Kit

The PD-SG1 is a dual transducer Switchgear PD detection instrument.  The unit detects TEV signals generated by internal discharge, as well as acoustic discharge generated by surface tracking or corona.

Partial discharge activity inside metal clad high voltage plant switchgear induces small voltage impulses (called Transient Earth Voltages) on the surface of the metal cladding.  TEV's travel around the cladding surface to the outside of the switchgear panel where they can be picked up extrenally using capacitively coupled transducers.

 

'Standard' Kit includes:

  • 1 x PD-SG1 handheld meter
  • 1 x Headphone set
  • 1 X Sync Transmitter and Function Tester
  • 2 x CC-TEV Sensor
  • 1 x AA Ultrasonic Sensor
  • 1 x HFCT Sensor
  • 1 x Operators Manual / Quick Start Guide
  • 1 x Pelican Transit / Storage Case

      

      

KEY PD-SG1 PRODUCT FEATURES

      • Ultrasonic detection of surface PD activity; display on the LCD as well as audible signal via headphone
      • Measurement of TEV signals generated by internal PD; display on the LCD in dB
      • Cycle Mode for viewing PD pattern in power cycle, allowing for the elimination of noise
      • Precedence Mode for location of PD in the assets under test
      • Bright LCD operator display panel for indoor and outdoor use
