Partial Discharge (PD) Surveys
EA Technology’s ability to detect, measure and interpret data gathered on Partial Discharge (PD) activity has revolutionised the management of assets used in substations.
Our PD surveys are carried out on live assets, without disruption, and include: (For more details on what Partial Discharge is then visit the

LEVEL 1: Initial PD Survey
TECHNIQUE
- First pass survey of assets, using UltraTEV instruments to check for critical PD activity
- Visual inspection
BENEFITS
- Identify assets at risk of failure
- Confirm assets that are problem-free
- Report and recommendations
LEVEL 2: Detailed PD Survey
TECHNIQUE
- Locate and quantify critical PD readings, using our full range of investigation instruments
- Expert interpretation and reports on condition data gathered
BENEFITS
- Detailed health of assets report
- Prediction of time-to-failure and end of service life
- Quantification of risk and consequences of failures
LEVEL 3: Ongoing PD Monitoring
TECHNIQUE
- Measure and analyse PD activity over time, using the UltraTEV Monitor system
- Install the UltraTEV Alarm system to provide alerts of critical PD activity in important assets
BENEFITS
- Accurate picture of how specific assets are deteriorating
- Early warning of potential failures in production-critical assets
- Effective asset performance monitoring in post-commissioning and post-repair phases
LEVEL 4: Tailored Services
TECHNIQUE
- Choose regular PD inspections as part of an ongoing service contract
- Combine any of the above PD activity assessments with our other condition assessment techniques
BENEFITS
- Upgrade asset management to fully condition-based
- Peace of mind assurance that you fully understand the condition of you assets
