SAFELY locates internal Partial Discharge (PD) activity in open terminal switchyards
The world’s most effective PD locator for switchyards
Benefits:
Prevents costly failures
Rapid return on investment
Gathers valuable data on asset condition
Extends asset life
Features:
Uniquely fast and accurate
Easy to use
Portable and rugged
Safe
Scan a whole Switchyard in minutes:
Switch on – the PD Hawk™ is instantly ready for action
Sweep the switchyard for radio emissions
Filter out irrelevant emissions e.g. mobile phone, television signals and non-destructive corona activity
Watch/listen to readings as they peak, to focus on the source of emissions
Rotate instrument for polarisation, to locate strongest signals
Use pulse mode to confirm emissions are PD
Note the strength and location of PD emissions
Rate the health of the asset and its risk of failure
Decide whether to investigate further and/or intervene
The PD Hawk™ Android App:
This unique application designed with the customer in mind captures data in two modes;
Pulse Mode and Scan Frequencies Mode. The PD Hawk™ Android App stores the captured data, enabling the operator to produce more accurate reports at a later date, it also allows results to be emailed instantaneously for further analysis.
The PD Hawk Android App is available on the Google Play Store*.
Fast Focus on Internal PD:
The PD Hawk™ measures emissions in the 47 – 1000 MHz frequency range with a default frequency of 800MHz, which is typical of internal PD activity. This enables the operator to disregard non-PD emissions, including harmless corona activity, and eliminate false readings.
Cost-Effective Outage Prevention:
The first sign of problems in switchyard assets is often sudden failure, causing expensive damage and outage.
The PD Hawk™ identifies problems in assets BEFORE they fail, at a fraction of the cost of a single outage.

Instrument transformers
Circuit breakers
Isolators
Disconnectors
Surge arrestors
