Identify corona discharge early. Protect performance, maintain safety and extend asset life

Corona discharge is an early indicator of poor asset performance for live components at high voltage so detecting it early can help you prevent developing issues with your assets before they become a problem.
PACE Networks provides corona detection surveys and reporting across rail and transmission & distribution infrastructure, helping identify issues early and support targeted maintenance.
Book a Corona Detection SurveyCorona discharge occurs when the electric field around live equipment ionises the surrounding air and can indicate contamination, poor connections, damaged fittings or component degradation.
If left unaddressed, corona can contribute to material ageing, power inefficiency and an increased risk of failure.
Detection requires specialist equipment and a targeted approach, providing clearer insight than visual inspection alone. Corona detection provides the greatest value to asset owners when inspections are repeated over time, showing data trends, the effects of maintenance, and the likely end of life.
PACE supports a range of inspection methods to suit different assets, access requirements and network conditions. We have cameras and software that work with:
Portable UV corona cameras allow targeted inspection of specific assets, structures or known problem areas. This approach is well suited to detailed condition assessments and follow-up investigations.
Corona inspection trolley providing efficient, consistent and repeatable results during foot-based inspections on flat surfaces and along railway track, reducing operator fatigue and improving productivity.
Drone-mounted corona cameras provide access to difficult or hazardous locations, reducing the need for possessions or working at height while maintaining inspection quality.
For network-wide assessments, vehicle-based systems enable efficient surveying across larger sections of infrastructure, supporting repeatable and scalable data capture.
For transmission networks and large-scale assets, aerial surveys offer rapid coverage over long distances, particularly where access is limited.


Each method can be deployed independently or combined to survey your asset as efficiently as possible depending on your setup and the scope of the survey.
PACE delivers corona detection surveys from planning through to reporting.
We develop a plan in line with your operational requirements for the structures/assets specified and carry out the data capture in the field with our corona camera. The captured data and any additional information is ingressed and then analysed with our software that produces asset specific recordings and insights for the survey.
Through collaboration with power system operators, PACE is able to support the transition from raw data to operational actions. Our monitoring reports show status and trends per asset and can include suggested actions.




For organisations using their own corona detection equipment, PACE provides reporting and analysis support and software.
The software analyses camera data to produce asset-level readings for each inspection. This information feeds into an interactive dashboard, giving a clear view of asset condition and performance over time. Historic readings and maintenance records are consolidated in one place, enabling trend analysis and, with sufficient data, reliable prediction of future performance.
SPEAK TO PACE ABOUT CORONA ANALYSIS SOFTWAREPACE corona detection surveys support a wide range of infrastructure, including:
By identifying corona activity early, asset owners can move from reactive maintenance to a more targeted, condition-led approach.
Corona detection provides a clearer picture of asset condition, but only when supported by the right approach to surveying and reporting.
PACE Networks combines equipment, field expertise and practical analysis to help asset owners make informed decisions, reduce risk and maintain reliable network performance.
