PRODUCT DESCRIPTION

EA Technology PD Hawk

With its highly directional antenna and selectable measurement center frequency the PD Hawk can easily be employed as a first pass safety tool for Switchyard entry or for the pinpointing and identification of individual PD sources as part of a full site survey.

Noise removal during PD measurements is often of concern, especially when employing UHF techniques. The PD Hawk addresses this by allowing a first pass sweep across its full 47MHz – 1GHz measurement band to allow the identification of ‘quiet’ frequencies. This simple and efficient first pass enables the user to tailor the measurement to the specific site allowing the identification of PD in subsequent measurements to be made with confidence.

The PD Hawk system is designed to be immune to the UHF emissions from Corona discharge. This allows the user to focus on the harmful surface and internal discharge, even in the presence of significant Corona.

The directional antenna of the PD Hawk™ enables problems to be identified in individual switchyard assets before they fail and at a fraction of the cost of a single outage caused by undetected problems resulting in disruptive failure.

The PD Hawk™ has the proven capability to locate PD activity in HV assets including:

  • Instrument transformers
  • Circuit breakers
  • Isolators
  • Disconnectors
  • Surge arrestors
  • Cable terminations and sealing ends
  • Transformer brushings

The PD Hawk™ Android App

Available to download from the Google Play Store, the PD Hawk App greatly enhances the functionality of the instrument. Designed with the end user in mind it captures data in two key modes; Pulse and Frequency Sweep Mode to help with the interpretation of detected discharge signals.

Linking directly to the PD Hawk™ the app allows the user to accurately locate the position of the measurement together with the captured data, enabling the operator to produce feature rich and accurate offline reports.

Need further assistance? The PD Hawk App allows the results to be e-mailed instantaneously for further analysis and support.
