Comprehensive Partial Discharge Surveys by EA Technology Australia
Partial Discharge Surveys
Knowing and understanding the condition of your power assets is vital in controlling the risks presented to your business, allowing your asset managers to plan and schedule your maintenance programme around actual asset condition rather than presumptions and set time intervals.
EA Technology’s Partial Discharge (PD) surveys are available worldwide, using our market-leading instruments. They are conducted by qualified personnel, who are expert at analysing the results to provide you with valuable reports on the condition of your assets. Our experts will provide you with an easy to understand, ‘traffic light’ status report which contains clear recommendations for managing your power assets based on their condition.
Why Measure PD Activity?
Put simply: Because 85% of disruptive substation failures are PD related. Once you have PD present, it will always increase and if left will inevitably cause a failure which may be sudden and catastrophic. PD is the most reliable indicator of the condition of insulation within live assets.
Benefits
- Prevent PD-related defects developing into failures and outages
- Collect valuable information on the health of assets and risks of them failing
- Enhance planning of maintenance and replacements, based on measured condition
- Improve network safety and reliability
- All testing is non-intrusive
- Comply with Health and Safety Executive’s HSG 230 (Health and Safety Guidelines Keeping Electrical Switchgear Safe)
Features
- Use of the latest instruments for detecting, measuring, locating, monitoring, recording and analysing PD activity
- Expert engineers, backed by EA Technology’s 50+ years expertise in PD
- Clear reports and recommendations on how to use PD survey results
- Instruments measure Ultrasonic activity, Transient Earth Voltages (TEVs) and in some cases Radio Frequency (RF) emissions
- Reliable, independent reporting using our database of 20,000+ test results to give you the most accurate conclusions
Our range of surveys designed to fit your needs:
Comprehensive Condition Assessment with PD Survey
Partial Discharge surveys can be carried out on:
- Indoor metal clad switchgear
- Outdoor switchgear
- Cable termination boxes of transformers
Other methods must be utilised to detect PD in cables or the windings of transformers/motors. Should the need arise, EA Technology has the expertise to deliver these customised test to meet your requirements.
PD surveys can be delivered as part of a larger package of condition assessment measures, such as oil sampling of transformers for dissolved gas analysis purposes and trip profiling of circuit breakers. Get in touch to find out more!
