What are the requirements for supplying power to a tunnel?
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).
How many kVA transformers should be installed in a tunnel?
A typical arrangement would be to install a 50 kVA step-up, 400:1000V transformer at the entrance to a tunnel and install 10 no. 5 kVA 1000:110V Tunnel Transformers at 300 metre centres along the tunnel (the transformers to be located at the mid-point of each 300M section).
What LV equipment do I need for a tunnel project?
A wide variety of LV electrical distribution equipment can be required on a tunnel project. Main LV supplies into tunnels are often provided with a back-up stand-by generator and our Mains Distribution Assemblies (MDAs) can incorporate Manual or Automatic Changeover systems to switch between Mains and Stand-by power.
What type of power does a tunnel need?
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).
