Automatic Electrical Asset Detection with Continuous-Learning AI

Registering each asset by hand was the bottleneck of the inventory for the tariff review. We automated that step with AI: less labour, faster delivery.

The Challenge

One of the largest electric power utilities in the State of Rio de Janeiro was carrying out the inventory of its electrical assets, a mandatory step of the tariff review regulated by ANEEL, Brazil's electricity regulator. To do the job, it hired Intellissis.

One of the inventory steps was registering each asset by hand: someone opened every field photograph, identified poles, transformers, medium- and low-voltage networks, fuse switches and identification plates, and typed it all into the system. With millions of photos, this step took up most of Intellissis's labour and set the delivery deadline to the utility.

Intellissis brought us that bottleneck. Our starting point was not the technology but the process: where the repetitive work is, what it costs, and what changes once it is no longer manual. The answer was an AI that detects and registers the assets on its own, and keeps getting more accurate with use.

The Solution: System + Method + Tool

System — Continuous Learning

Each inspection generates data that feeds back into the model. Operators validate or correct detections, and this feedback automatically triggers a new retraining cycle. The most accurate model is promoted to production without manual intervention.

Method — Structured Pipeline

From archive indexing to assisted annotation, auditable training, automatic promotion of the best model, and an operational feedback loop. A replicable process from data collection to production.

Tool — Real Integration

Production REST API and .NET/C# SDK integrated into Intellissis's Windows systems, with no infrastructure migration. The registration team started using AI without realising they were dealing with machine learning.

17 classes + automatic OCR

In addition to detecting 17 asset types, the system automatically reads the text on identification plates — extracting power rating, manufacturer and asset tag.

What this case says about your process

Here the tool was object detection in images, because the bottleneck was looking at photos and registering what appeared in them. For another client the bottleneck may be reading documents, checking spreadsheets, reconciling entries or scheduling a team. The technology changes; the method stays the same.

We map the process, find the step that eats the most hours and the most lead time, and build the automation that solves that step, integrated with what your team already uses. The result that matters is not the AI itself: it is lower labour cost and faster delivery to your own client.
