1. Contact the construction unit or site administrator, explain the reason for using a generator, and ask if there is a generator available.
2. If the construction unit or site manager cannot provide a generator, you can contact your own supplier or rental company to rent a generator.
1》There is basically no sensation of electric shock with a simple generator output, because the generator windings are isolated from ground and the windings and ground form a very small distributed capacitance if generator output power; The power network is large, the electrical power network Although it is isolated from the earth, the capacity distributed with the earth cannot be ignored. The wider the power supply network, the greater the distributed capacity and the stronger the electric shock, which is approximately. 380 V.
2》est the same as point 1》, and the same as the three-phase high-voltage power line.
3》It must be grounded through the zero line (neutral line) to be effective. When an electric shock occurs, the voltage is much lower and can be used as grounding for the shell of electrical equipment. avoid electric shock or other accidents. Otherwise, it's the same as the 2 points above.
