Substations cannot afford blind spots.
Manual inspection is reaching its limits

WHY THIS “AUTONOMOUS VISUAL INSPECTION AND ASSET MONITORING” CHALLENGE?

Manual checks can’t keep pace with substation risk

High voltage substations are critical to uninterrupted power supply, yet traditional checks are time-consuming and risky for field teams. Uneven terrain and energized equipment make routine monitoring harder when accuracy matters most

Key benefits

Safer Inspection Starts With Fewer People in Harm’s Way

Send the robot before the technician

Reduce exposure by using autonomous systems for routine checks in high-voltage environments

Spot anomalies across multiple signals

Combine visual imaging, 3D mapping, thermal sensing and partial discharge detection for richer asset insight

Navigate where inspections get difficult

Move across uneven terrain, obstacles and mixed surfaces to reach relevant inspection points autonomously

Turn alerts into targeted action

Send alarms to the control room so teams can verify remotely and dispatch crews only when necessary

How NTT DATA helps

01

Autonomous inspection use-case design

Robotics is mapped to where it adds the most value across substations, from recurring visual checks to anomaly-driven maintenance

02

Sensor and navigation architecture

Inspection capabilities are built around visual cameras, 3D mapping, thermal imaging, and electrical anomaly detection

03

Remote supervision and teleoperation model

Operational teams keep control, with real-time robot data, remote verification, and teleoperation available when needed

Implementing real-time segmentation engines

04

Integration with control room workflows

Alerts, inspection data, and remote checks connect into existing operational processes so anomalies become actionable decisions

05

Scalable deployment foundation

The solution industrializes so new sensors, routes, and inspection needs can be added as the operating model matures

Cloud-ready portals for resilient utility service

Proven impact

Fewer exposed technicians, faster detection

Smarter substation maintenance follows when anomalies surface before they become operational risk

Results that matter

Operational Gains From Autonomous Inspection

Reduce field exposure

Shift routine inspection tasks away from manual checks in energized or difficult-to-access areas

Accelerate anomaly response

Enable immediate alerts and remote verification when potential issues are detected

Improve inspection consistency

Standardize routes, sensing and data capture across recurring substation monitoring activities

Optimize maintenance dispatch

Send operational teams only when remote inspection confirms that intervention is needed

Make substation inspection safer, faster and more precise

Deploy autonomous monitoring where uptime, safety and asset reliability matter most→
