OMEXOM appraisals the condition of substations on the basis of such varied criteria as:

	Climatic aggression,
	The environmental context,
	The functioning mode,
	Overhauls and inspections made,
	The measurements taken and surveys made, power on or off.

OMEXOM's analysis and assessment capacity is based on the skills and experience of its engineers and technicians, in the design office and on site.
OMEXOM's teams frequently use design calculation software and high-tech equipment (infrared cameras, current and power generators, harmonic analysers, oscilloscopes…), which are sure-fire guarantees of technology and efficiency at the service of the client
