Spark P3

Universal PD & EMI analyzer

Doble Spark P3 is a universal partial discharge (PD) and electromagnetic interference (EMI) analyzer that uses a software defined radio signal detector to identify characteristics of insulation system deterioration that could lead to the failure of high voltage equipment. It detects signals from suitable sensors in a frequency range between 9 kHz to 2 GHz for PD and EMI, and DC to 500k Hz for acoustic and reference voltage measurements.

An automatic classification system enables users of all experience levels to easily distinguish partial discharge activity from nuisance signals and classify different types of PD/EMI defects in high-voltage apparatus, including:

  • Rotating machines (PD couplers, HFCT sensors)
  • Power transformers (HFCT sensors, UHF antennas, acoustic microphones)
  • Instrument transformers (HFCT sensors)
  • Switchgear (GIS and AIS – TEV sensors, UHF antennas, HFCT, acoustic sensors, spacer
    sensors, window sensors)
  • Cables and accessories (HFCT, UHF sensors, acoustic sensors)

Guidance for Inexperienced Users

A “Wizard Mode” guides users new to the subject through the measurement and data acquisition procedure, limiting functionality and other elements to the minimum required to conduct the task. More experienced personnel can select “Expert Mode” to configure the system to perform measurements in any desired form.

  • Automatic signal fault classifier
  • Universal detector applicable for most PD testing scenarios
  • Guided mode for minimum operator training requirements
  • Freely configurable and pre-set test plans for any application and automatic data acquisition
  • Battery operated benchtop (lab) or Pelicase (site), 19inch rack-mount adapter available
  • Signal classification algorithm helps inexperienced operators obtain reliable results
  • Guided measurements
  • Automatic measurements and test plans (can be edited)
  • Suits most PD/EMI applications
  • Lightweight battery operated device (suitable for cabin and hold air travel)
