How Partial Discharge Detection Prevents Outages
EXPLORE
Distribution Grids are Under Growing Pressure
Electrification, renewable energy integration, aging infrastructure, and increasingly complex power flows are placing greater demands on power networks.
Utilities are under pressure to improve SAIDI and SAIFI performance, while renewable energy operators, industrial facilities, and data centers must protect uptime, safety, and operational continuity.
- Limited network visibility - Developing faults and abnormal conditions can remain hidden until they disrupt service.
- Reliability and uptime pressure - Slow fault location and restoration can increase SAIDI and SAIFI, reduce energy availability, and extend operational downtime.
- Growing safety risks - Aging assets, energized equipment, and harsh underground environments increase risks for people, communities, and infrastructure.
- Rising operational pressure - Manual inspections, emergency repairs, and skilled labor constraints make traditional maintenance increasingly difficult to sustain.

Build More Resilient Power Networks
Every power network has different priorities, constraints, and levels of digital maturity. We help utilities, renewable energy operators, industrial facilities, and critical infrastructure identify where greater visibility, earlier detection, or increased automation can deliver the most value, and then support a practical path forward.
From local indication to predictive monitoring and automation, our solutions can support safer operations, more informed maintenance, and greater continuity of service across new and existing power networks.
Predict earlier
Identify partial discharge, transient faults, and abnormal conditions before they lead to failure.
Detect faster
Locate faults quickly across overhead, underground, and critical power networks.
Re-energize sooner
Support faster isolation, switching, and restoration to reduce downtime and protect continuity.
