Tunnels
Tunnel uninterruptible power supply (UPS) and battery back-up systems; Tunnel earthing system and lightning protection; and Tunnel cable containment systems. The objective of this Master
Most of the tunnel equipment and systems require electrical energy to operate. Therefore, equipment for supplying power to the tunnel must be installed. This installation has to satisfy two essential requirements: Meet the needs under all operational situations (normal, degraded, critical, emergency).
However, some identical principles can be noted, such as: The installation of a device that can compensate for a total loss of power supply. This system (uninterruptible power supply (UPS), diesel generator., etc.) supplies electricity to equipment critical for safety, during a limited period of time.
Meet the needs under all operational situations (normal, degraded, critical, emergency). The power required for supplying a tunnel is directly related to the nature and number of equipment installed in it. Depending on the amount of electrical energy required (kWh), power may be supplied in low voltage or high voltage (Fig. 1).
