The insulation breakage measuring device producer is joining Ampacimon having launched out of Polytechnic University of Madrid over ten years ago.

Diael, a Spain-based energy infrastructure maintenance technology provider extending Polytechnic University of Madrid research, has agreed to be acquired by grid monitoring products supplier Ampacimon for an undisclosed sum.

Founded in 2010, Diael has launched a portable device for measuring insulation breakages in small sections of energy cables and transformers – a grid maintenance problem known as partial discharge.

The acquisition is expected to boost Ampacimon’s expertise in monitoring underground cables, complementing its existing expertise in overhead infrastructure.

GUV could not confirm whether the spinout had raised equity prior to the acquisition. Ampacimon itself is a spinout, too, having emerged out of University of Liège also in 2010.
