Start-up founded in 2016 with the aim of offering technologically advanced solutions in public transport, especially in the management of electrical infrastructure. EFS (Energy Flow Simulation) was the starting point for this project, offering an online platform where users could directly simulate their network in different scenarios. The introduction of sensors on the contact wire was a second step towards the implementation of the Smart Catenary concept, introducing sensors for acceleration and vertical displacement of the contact wire, temperature and traction force. All of this, together with our team of highly qualified engineers, allows us to offer advice advancing the efficient management of electrical energy in the network.
