One of the key aspects of electricity infrastructure management is maintenance. In substations and electricity plants in particular, analysis and testing of insulating oil make it possible to carry out extra preventive and predictive maintenance.
Endesa Ingeniería has its own Chemical Laboratory predominantly dedicated to improving transformer diagnosis and maintenance procedures.
The Laboratory is recognised internationally and holds ENAC accreditation (www.enac.es).
Its services cover all aspects which may affect the useful life of a transformer:
Control and reception of new oils
Control of oils in service
Electromagnetic circuit assessment
Cellulose insulation assessment
Environmental impact assessment for insulating oils
(PCBs, PHAs, benzopyrenes, etc)
