Overview

The Doble Spark P3 is a universal partial discharge (PD) and electromagnetic interference (EMI) analyser 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.

A comprehensive range of detectors, acquisition and analysis tools enables users of all levels to acquire and review partial discharge and EMI signals, covering a wide range of test objects and usable sensors, 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)

Features

• 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

Benefits

• Automatic data acquisition methods help inexperienced operators to 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)
