Problems solved by technology

[0002] In power transmission, high-voltage power transmission is often used for transmission. According to the principle of voltage transformation with constant power, when the voltage increases, the current will decrease accordingly. At this time, the loss generated during high-voltage power transmission will decrease, but The threat of high-voltage electricity to people is quite great. Every year, incidents of serious injury or even death of people due to high-voltage electricity accidents occur from time to time. For such invisible and intangible things as high-voltage electricity, it is difficult for people to take measures to avoid electric shock.
