Inspection and maintenance of substations
Electricity facilities should undergo regular maintenance to ensure the quality of their operation. The possible failure of a substation is a situation that requires urgent action, as any interruption in its operation generates significant costs. Therefore, regular and professional maintenance of substations and rapid elimination of the source of failure is very important. In such situations, time and speed are of the essence, as well as the permanent and effective elimination of failures. Alterga’s specialists are not only qualified and experienced, but also have advanced equipment to perform detailed diagnostics of individual devices and qualitative measurements of specific parameters.
Scope of substation inspection activities
Maintenance inspections of power facilities consist of detailed visual inspections, measurements and tests to assess the technical condition of the facility and its components. For example, the substation maintenance inspection may require:
- topping up and replacing electrical insulating oil in station equipment
- replacement of insulation
- measurement of the quality of lighting and its possible replacement in substation facilities
- cleaning and assessing the technical condition of insulators and other equipment
- replacing individual elements of substation objects
- measuring and checking the condition and operation of anti-shock protection systems
- checking the status of documentation and providing records related to the scope of maintenance work carried out
All the services indicated above, and many more, are part of Alterga’s comprehensive offering – testing, inspection and operation of power facilities and substations from 0.4 kV to 750 kV.
