It is hard to imagine life without electricity. Electrical energy is constantly consumed to allow humanity to carry out diverse activities ranging from charging mobile phones to controlling the flow of vehicles and pedestrians with traffic lights. Due to its widespread usage and significance, some people take the availability of electric power for granted and expect that the lights will always turn on when they turn on the switch. Nevertheless, when illuminating our rooms, we need to appreciate that an extensive power system infrastructure is in place to securely generate, transport, and distribute electrical energy to our homes.

增强传输安全性的愿景：瑞士电力系统的案例

很难想象没有电的生活。不断消耗电能，以使人类能够进行各种活动，从给手机充电到控制带有交通信号灯的车辆和行人的流量。由于其广泛的用途和重要性，一些人认为电力的可用性是理所当然的，他们期望在打开开关时灯始终会点亮。尽管如此，当照亮我们的房间时，我们需要意识到，已经建立了广泛的电力系统基础设施，可以安全地为我们的房屋发电，运输和分配电能。
