I am going to tell you about a specific experience that became one of our success stories in Uruguay. This company has a distributed infrastructure in the city. At each site there are signs that are illuminated at night. The lighting was switched on and off by means of clocks whose adjustment were done manually on site.

When we asked them how they made sure the system was working properly, the answer was that, during the nights, they did periodic rounds of visual inspection. On the other hand, if they had to modify the ignition times, they also did it by going to the site to make the necessary adjustments to the clock. “We already solved that problem” was the answer to our questions.

Sometimes the eventual fault would appear after the site inspection. In the best of cases the problem was detected in the next round of inspection; at worst, it was the customer who detected the problem and made the claim. In all cases, some posters were not properly illuminated for several nights.

Despite the perception of the company that they did not have a problem, they trusted Nettra. We implemented our IoT solution with energy consumption sensors connected to our RTU-X, which also started to control the contactor that energizes the lighting. Inspection rounds are no longer necessary because knowing the nominal consumption, the system automatically alerts when the values ​​deviate more than a certain threshold.
