Installation must address foundation strength, lifting and handling methods, clearances, grounding, and routing of high-voltage connections. Oil filling and vacuum treatment are done under controlled conditions. Cooling, ventilation, and access for maintenance must be planned. Protection and control wiring, CT/VT connections, and communication links must be properly terminated and tested. Environmental factors such as flood risk, lightning exposure, and fire barriers are accounted for. Finally, commissioning tests verify installation integrity before energization.
