Electrical Insulation Diagnosis

The company ‘Diagnóstico del Aislamiento Eléctrico, S.L.’ (DIAEL) grew out from a research sponsored in 2006 by ‘Unión Fenosa Distribución’ (UFD) in the field of partial discharges which was developed within the ‘Polytechnic University of Madrid’ (UPM) in close collaboration with the ‘Laboratorio Central Oficial de Electrotecnia’ (LCOE). Such research materialized in a new system of measurement and monitoring of partial discharges for High Voltage cables.

Additional researches conducted between 2009 and 2012 have allowed to extend the developments to the field of cables to the areas of Power Transformers and Gas-Insulated Substations (GIS).

Also, DIAEL has expanded its range of products and services in the area of High Voltage testing and measuring techniques with temperature measuring equipments by means of optical fiber, systems of generation and measurement of lightning impulses, etc.

BlueBOX Technology is characterized by the use of powerful numerical tools in the service of the high voltage insulation diagnosis in severe operating conditions.

DIAEL is a spin-off of the UPM with headquarters in Madrid created in 2010, specialized in measurement techniques of high technological level based in the signal processing.

DIAEL is advised by a committee of experts with extensive experience in the field of high voltage tests and measurements formed by professors and high qualified personnel.

DIAEL participates actively in numerous national and international conferences (CIGRE, CIRED, SMART GRIDS, ALTAE, MATELEC, …).

DIAEL has expanded its international sales network by establishing agreements with large companies that allow it to position itself in multiple countries all over the world.
