In this video, we demonstrate how live power line maintenance is performed using helicopters, a cutting-edge technology that ensures the continuous flow of electricity without the need for power outages. This technique relies on the principle of working at the same voltage, which is key to protecting workers from electric shock when handling live power lines. As the worker approaches the power line using the helicopter, they are connected to the line so that both the worker and the line are at the same electrical potential. This means there is no voltage difference between the worker and the line, and therefore, no current passes through the worker's body. Electric current always flows from a higher voltage to a lower voltage, but since the worker and the power line are equal in voltage, no current flows. The helicopter itself does not get electrocuted for several reasons. First, the aircraft's structure is made from insulating materials that prevent the flow of electricity. Second, the
