Why monitor partial discharge?
Partial discharge is a localized electrical discharge within or on the surface of insulation. Its development over time provides data for investigating an emerging defect. A single signal does not, by itself, establish the exact time of failure or the required maintenance action.
How does PDEye work?
PDEye monitoring has three stages:
- Data collection: Suitable sensors collect partial discharge signals from cables and other electrical assets. Field devices can also work with additional data such as temperature and humidity.
- Analysis: Data reaches a central platform. Software filters signals and evaluates changes over time.
- Alert and investigation: Potential defects and their severity are presented to the maintenance team. The team considers site conditions and any necessary tests before deciding what to do.
What does the maintenance team gain?
- Visibility of changes in partial discharge activity over time
- Earlier opportunities to investigate cable joints, terminations and insulation defects
- Prioritized alerts about possible defect type, location and severity
- Data sharing with SCADA and asset management systems
The manufacturer says that its AI-supported PDEye platform analyses partial discharge data and generates alerts. An alert does not replace on-site verification, maintenance decisions or necessary tests.
Where is it used?
The manufacturer lists underground power cables and accessories, transformers, GIS and switchgear among its applications. Sensor type and monitoring scope are selected for the asset.
See the PDEye brochure for system architecture and application details.
How does it relate to periodic testing?
Online monitoring helps track changes that develop between tests. Periodic testing and site inspections have a separate role in confirming findings and planning intervention.
Frequently asked questions
Is PDEye used only for underground cables?
No. This ASIVA solution page focuses on cable diagnostics, while the manufacturer also lists transformers, GIS and switchgear. Sensor selection depends on the asset.
Does an alert pinpoint the fault with certainty?
An alert makes activity and its priority visible for investigation. Location and a definitive diagnosis depend on sensor placement and on-site verification.
Can it connect to existing SCADA infrastructure?
The brochure mentions SCADA and asset management integration. The data and connection method are defined after reviewing the existing infrastructure.
