With the rise of EV chargers and heat pumps, low-voltage transformers are overheating. The ACE6000 measures transformer temperature indirectly (by measuring the line resistance shift over temperature) and reports back to the Distribution System Operator (DSO). This allows for —the grid can tell a new EV charger to wait 10 seconds before ramping up power, preventing a brownout. Conclusion: The Invisible Interface The Itron ACE6000 is the perfect example of the invisible computer . It sits in a cold, damp meter box, never touched by its owner, yet it governs the financial transaction, the physical safety, and the data intelligence of a home. It is not just a compteur (counter); it is an arbitrator between physics, economics, and human behavior.
