WHY THIS “AUTONOMOUS VISUAL INSPECTION AND ASSET MONITORING” CHALLENGE?
Manual rounds no longer keep up with substation risk High-voltage substations keep the grid alive, yet technicians still walk energized yards to log routine readings.

Rough terrain and live equipment slow every check, right when speed and accuracy matter most.

Key benefits
Send the robot first, keep your team out of harm’s way

Fewer people near live equipment:

The inspection robot walks the yard on routine rounds, so your technicians stay clear of energized equipment and uneven terrain.

One robot, four ways to spot a fault:

Visual cameras, 3D mapping, thermal imaging and partial discharge sensors work together on a single pass, so a fault rarely hides.

Built for the ground technicians struggle on:

Gravel, stairs, cable trenches and mixed surfaces slow a human round. The robot crosses them on its own, reaching points a special trip once required.

Alerts first, people only when needed:

Every anomaly reaches the control room first. Your crew verifies remotely and rolls out once the data confirms a visit is worth the trip.

How NTT DATA helps

01
Route and checkpoint design

Field data shows where downtime and safety risk concentrate most, and robotic rounds get built around those points first.

02
Anomaly detection architecture

RGB cameras, 3D lidar, thermal imaging and partial discharge detection combine into a single inspection platform built for energized yards.

03
Remote supervision and teleoperation

Your operators keep control, with real-time robot data, remote verification and teleoperation available whenever a judgment call is needed.

04
Control room escalation

Alerts, inspection data and remote checks flow into the workflows your team already runs, so an anomaly turns into a decision your team acts on right away.

Alerts, inspection data and remote checks flow into the workflows your team already runs, so an anomaly turns into a decision your team acts on right away. 

New sensors, routes and substations add onto the same model as your inspection program grows, without a redesign each time.

Proven impact
Substation inspection at scale

Fewer technicians in energized yards. Faster anomaly detection. Maintenance planned around real asset condition, not a fixed calendar. 

Results that matter
Operational gains from autonomous inspection
check icon
Fewer people in the yard

Routine substation rounds shift from technicians to the robot, cutting exposure in energized and hard to access areas. 

check icon
Faster anomaly response

Alerts and remote verification cut the time between a signal and a decision to dispatch a crew

check icon
Consistent inspection data

The same routes, sensors and checkpoints run every time, so comparisons across rounds hold up.

check icon
Fewer unnecessary truck rolls

Crews deploy once remote data confirms a visit is worth the trip. 

Never let a substation go unseen

Shape the conversation that keeps your substations safe, seen and running, before risk becomes downtime
