Prevent breakdowns. Extend the lifespan of your installation. Prepare your substation for the annual inspection.
A high-voltage substation is a crucial link in the power supply of your building or business. Yet it often receives attention only when a fault occurs or when defects are identified during the annual inspection.
As Built helps you stay ahead of problems. Through periodic technical maintenance, we assess the condition of your high-voltage installation, identify potential defects and help you manage the installation safely, reliably and with proper documentation.
Electrical components are subject to ageing, contamination, mechanical stress and thermal stress. Loose connections, dust, wear or defective components can remain unnoticed for a long time – until a fault occurs.
In a high-voltage installation, a fault can have major consequences:
Preventive maintenance helps identify such problems in good time.
Hoogspanningsinstallaties moeten in België in principe jaarlijks periodiek worden gecontroleerd door een erkend controleorganisme. Deze wettelijke controle mag niet worden verward met het technisch onderhoud van de installatie.
De controle stelt vast. Het onderhoud voorkomt en verhelpt.
Door het onderhoud vóór de periodieke controle te plannen, kunnen zichtbare of gekende technische tekortkomingen waar mogelijk vooraf worden aangepakt. Zo komt u beter voorbereid aan de wettelijke controle.
FAQ
The appropriate maintenance frequency depends on the type of installation, its environment, the load and
the manufacturer’s instructions. In practice, regular checks and maintenance are strongly recommended
to detect faults and wear at an early stage and help prevent unplanned outages. As Built can prepare a
maintenance plan tailored to your installation.
A high-voltage installation must be operated safely and kept in good condition. The specific obligations
depend on the installation and the applicable regulations. As Built works with you to identify the periodic
checks, inspections and maintenance tasks that apply to your installation.
We check, among other things, the general condition of the substation, high-voltage switchgear units,
transformer, protective devices, connections and earthing, as well as visible signs of wear,
contamination, overheating or damage. The exact scope of work is tailored to the type and configuration
of the installation.
Certain checks and maintenance tasks require a power shutdown. We prepare the work in advance and
agree the timing of the shutdown with you to minimise the impact on your business activities.
This depends on the size, type and condition of the installation. When preparing the maintenance visit,
we determine the work required and provide a clear estimate of the expected duration and any necessary
power shutdown.
Yes. Preventive maintenance is specifically intended to detect abnormalities and wear at an early stage.
Where appropriate, additional checks, measurements or thermal imaging can be carried out to identify
potential problem areas in good time.
We clearly document the defects identified and advise you on the action required. If modifications or
repairs are necessary, As Built can provide a separate proposal and coordinate the work.
Yes. Following the maintenance visit, you will receive a clear maintenance report detailing the checks
carried out, relevant findings and any recommendations. This provides a record of your installation's
condition and maintenance history.
Yes. In addition to periodic maintenance, As Built can address non-compliances identified during an
electrical inspection. We analyse the inspection report, determine the necessary work and manage the
process until the installation has been brought back into compliance and is ready for re-inspection.
Yes. As Built can manage the periodic maintenance of your high-voltage substation on an ongoing basis.
This means you do not have to arrange each subsequent maintenance visit yourself, while retaining a
clear overview of maintenance, findings and any work that needs to be carried out.
Yes. Older installations can also be maintained. For older substations, we pay particular attention to the
condition of components, wear, the availability of spare parts and potential risks. If modernisation is
advisable, we will discuss this with you separately.
As Built focuses on commercial and non-residential installations, including business premises, offices,
apartment buildings, shops, logistics facilities and other buildings with their own high-voltage substation.
Yes. This is precisely the benefit of having a single point of contact. If problems are identified during
maintenance, we can not only report what is wrong, but also propose the necessary modifications or
repairs and organise the work.
