Eaton to deploy energy harvesting sensors with its xEnergy switchgear system
Micropelt GmbH and Eaton have signed an agreement for the delivery of an innovative diagnostic system, which is to be used in Eaton's tried and trusted xEnergy low-voltage switchgear.

This collaboration will allow Eaton to offer its customers enhanced capabilities for maximizing the safety and availability of their electrical equipment.

The Micropelt diagnostic system will include a self-powered temperature sensor that can be installed in any location, or mounted anywhere on the busbar. It draws its own power from the alternating electrical field of the current-carrying conductor, via inductive energy harvesting.

At a current intensity as low as 50A, the sensor thus generates enough energy for measuring temperature and transferring data. The measured values are reliably transmitted at 2.4 GHz using wireless technology according to the IEE 802.15.4 standard—either directly to the control system or to the Linux-based server. The measured data can be stored and processed in real time. The functionality includes plausibility checks as well as the ability to create trend analyses. If the user-defined limits are exceeded, an alarm message is generated and sent to the mobile phone of the person in charge as well as to the control center.
