The PD Hawk™ is uniquely effective for detecting and locating Partial Discharge (PD) activity in open terminal switchyards. It is also a highly effective instrument for detecting PD problems in cable joints and sealing ends.
With its highly directional antenna and selectable measurement centre 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 sources as part of a full site survey.
Operating in the UHF spectrum, the PD Hawk is able to ignore non-destructive corona activity that is often present in high voltage switchyards.
Narrow band noise sources in the UHF spectrum can also cause interference. 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 users’ confidence in PD identification and detection is further increased by the ability to listen to a heterodyned version of the emissions via the built-in speaker or headphones; whilst simultaneous being able to monitor the activity on the in-built display.
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:
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. ,

Failure of your high-voltage switchgear and cabling could cost millions in repairs, replacements and fines. But most failures don’t happen in a flash – they can be predicted from warning signs, most notably partial discharge (PD). By watching your cables and switchgear, EA Technology’s Astute HV Monitoring® service can alert you to suspicious spikes and pinpoint which parts of your HV system should be investigated.
