Power Quality Surveys
Diagnose, Optimise and Protect Your Electrical Systems
Unstable voltage, harmonics, or power disturbances can lead to equipment failures, reduced efficiency, and costly downtime. Our power quality surveys identify the root causes of these issues – giving you the insight and data needed to make informed improvements to your electrical network.
Whether it's a reactive investigation or preventative monitoring, we deliver the information and solutions you need to maintain performance and reliability.
Our Expertise
- Detailed on-site power quality measurements using certified and calibrated power quality analysers.
- Analysis of voltage stability, harmonics, flicker and unbalance.
- Identification of equipment causing distortion or interference.
- Custom reporting for internal engineering teams or for DNO reference.
- Nationwide coverage with rapid deployment and professional comprehensive reporting.
When to Book a Power Quality Survey
- Experiencing unexplained equipment trips or failures.
- Energy inefficiency or rising power bills.
- Intermittent disturbances in control or automation systems.
- Before installing new loads such and variable speed drives, motors or renewable energy sources.
- Periodic maintenance and performance audits.
This helps to avoid costly downtime, extend equipment lifespan and maintain compliance with power quality standards such as ENA ER G5/5 and IEC 61000.
Our Survey Process
- Initial consultation – we discuss your site, systems and known issues. We will gather information to inform us how we can monitor the supply.
- Site based measurement – we will install certified and calibrated power quality analysers to capture real data (typically over 7-days, or as requested).
- Data analysis and reporting – we will evaluate the harmonics, voltage everts, flicker and all other power quality phenomena that may be present. These will be detailed in a clear and comprehensive report.
- Recommendations – we will advise practical steps to mitigate issues and enhance the network performance.
All results are presented in clear report that is easy to interpret, with graphs, trends and specific details.
The Benefits
- Reduce unscheduled downtime and maintenance costs.
- Improve system efficiency and equipment lifespan.
- Maintain power quality compliance and network stability.
- Obtain data-back insights for planning and upgrades.
