HV / MV substations
Engineering and integration of substations, switchgear and equipment required for the reception, transformation and distribution of electrical power.
HV / MV / LV Electricity
Designing and securing critical electrical networks.
WOLDIUS ENERGY supports the design, integration, commissioning and maintenance of high-, medium- and low-voltage electrical networks for industrial, institutional and territorial infrastructure.
Network architecture
HV → MV → LV: an electrical chain engineered as one system.
High-, medium- and low-voltage networks form the backbone of industrial, institutional and territorial infrastructure. Their reliability directly affects operational continuity, personnel safety and equipment availability.
The final architecture is determined following an assessment of the existing network, electrical loads, energy sources and site-specific constraints.
Substations & transformation
Structuring power transformation and distribution.
Transformers
Sizing, integration and connection of transformers, including protection requirements and operating conditions.
Distribution & protection
Distributing electrical power with selectivity, safety and continuity.
HV / MV substations
Substation architecture, switchgear, transformers, protection systems and interfaces with existing electrical networks.
LV distribution
Main and secondary distribution boards, switchgear, selectivity, protection systems and continuity of supply for critical loads.
Electrical protection
Protection coordination, circuit breakers, relays, selectivity and fault management across multi-source electrical networks.
Earthing systems
Equipotential bonding, earthing networks and protective arrangements designed to improve installation safety and reliability.
Supervision
Monitor and understand the network.
Monitoring of equipment, alarms, electrical parameters, events and infrastructure availability.
