MAINTENANCE TO ELECTRICAL SUBSTATIONS

Substations, plants and UPS's

Preventive care of any electrical substation and corrective service to electrical transformers is essential to ensure continuity in the operations of any industrial complex.

 

The analysis of the physical-chemical state of the transformer oil is recommended annually, it is suggested to carry out insulation resistance tests, transformation ratio, duct tests and also the ground system to verify the state of the substation.

 

Altos Ingeniería Eléctrica offers a preventive and corrective Industrial Electrical Maintenance service, as well as various tests and studies:
