RGIE Book 2 · BELAC ISO 17020
High-voltage cabin inspection
Inspection of your industrial high-voltage cabin (HV/LV transformer station) per RGIE Book 2. Required for sites > 100 kVA, factories, hospitals, large commercial buildings.
The high-voltage cabin inspection is governed by RGIE Book 2 (Royal Decree 8 September 2019). It applies to all industrial and tertiary sites equipped with an HV/LV transformer station — typically buildings with peak power above 100 kVA: factories, logistics centers, hospitals, large office complexes, hotels, shopping centers.
This is a specialty that few inspection bodies offer in Belgium because of the technical expertise required. Atlas Contrôle is one of them.
Commissioning (acceptance)
Mandatory inspection before a new, modified or refurbished HV substation is energised. Full verification against RGIE Book 2 before it is coupled to the grid operator’s network. The acceptance report goes to both the installer and the operator.
Annual periodic inspection
Mandatory yearly check of HV installations in service. Testing of the protection devices, insulation measurements, earthing check, verification of the isolation and emergency shutdown devices.
Industry & workshops
Transformer substations for factories, workshops and production sites. Often substantial capacity (630 kVA transformers up to several MVA) and sometimes several HV cells.
Buildings & co-ownerships
HV substations in office buildings, large residential co-ownerships and shopping centres. The managing agent or the technical manager is responsible for keeping them compliant.
Critical premises
Hospitals, clinics, schools, data centres, public buildings: electrical availability is critical. Our inspection also covers the backup sources (generators, UPS) and how they fit into the HV single-line diagram.
Report and detailed findings
Full report, verified single-line diagram, recorded measurements, and preventive maintenance recommendations. Documents accepted by insurers, grid operators (Sibelga, ORES, Fluvius) and the authorities.
Transparent pricing
Prices include VAT, no surprises. Personalised quote within 24h.
