Cloud – Online Partial Discharge Monitoring

Our Cloud enables online partial discharge monitoring from the detect/locate/monitor portfolio using three main functions: data processing, alerting, and hosting our NServer web app.

The NServer web app provides a user interface which facilitate further interrogation on any system whether live or historical.

Options also exist for mapped and non-mapped systems. For non-mapped systems, for example, where sensors are directly connected to GIS, data is unique to each sensor. For mapped equipment, i.e., over air detection, a map overlay of site is displayed showing the PD source location.

  • Secure access with user permissions
  • Central dashboard showing all connected sites & systems for efficient online partial discharge monitoring
  • Different view selections for each system: PD Results, PD Trends, Summary, Activity, Alerts
  • Weather data available (optional added feature on the PD Trends charts)
  • Historical equipment views available


  • Rapid Response

    We can respond quickly to urgent survey requirements. Once on site, a survey can be conducted in a few hours. The associated report is usually prepared within a week of the survey date.

  • Self Contained

    There is no requirement to connect the vehicle within the substation; everything is contained within the vehicle. Using our software, the operator can monitor activity while moving. Once PD is found, the vehicle moves into different positions to pinpoint the source.

  • Utilises Our Expertise

    Some of the effects measured by the system will be benign (e.g.: dry-band arcing); but most PD emissions represent dielectric stresses that should not be present in high-voltage equipment. From our extensive experience in performing surveys, we are able to distinguish between benign and problematic emissions. This experience enables us to create an informed, accurate report on the survey, along with our view on how to tackle each PD issue.

  • Flexible

    Radiometric PD Surveys can be used to supplement our Elimpus PD detection system, by locating the source of any partial discharge activity detected by the unit. Radiometric PD Surveys are also ideal for use as part of a regular preventative maintenance schedule.
