When the flood is high, as long as you are not careful, you will not be electrocuted if you wander near a telephone pole.
-
The stronger the voltage, the greater the safety distance. Water has electrical resistance, and the higher the purity of the water, the higher the resistivity. However, generally water purity is low
-
First of all, electricity leakage is infrequent, and floods are even rarer, and they are transmitted to the earth through conductors.
-
1. The wires are not broken, so the electricity is still connected to the normal load end (home, factory).
2. The ground wire in the immersion is the neutral line.

All of the following are possible. 1. The wire is not broken, so the electricity is still connected to the normal load end (home, factory) 2. The ground wire in the water is the neutral wire.
-
After all, electrocution in the water is not so easy to happen, first of all, electricity leakage is not common, and floods are even rarer.
-
Electricity leakage is dangerous. Under no circumstances should you enter water with a voltage of 220V.
-
I think it's because it's protected by protective measures, so it won't be electrocuted.

Non-conductive cloth. Will go into the franchise, so it won't. Electric shock.

Because the water is a conductor, and the earth is also a conductor, electricity can be directly introduced into the earth through the water, so when there is a flood, the personnel are fine!
There is also vertical width, and now there are short-circuit tripping equipment, water will cause a short circuit, and then the equipment trips, and the power supply will be cut off!
Yours is my motivation to move forward, and if you still don't understand something, please continue to "ask"! Sedan car!!
If you have new questions, you can ask me for help, it is not easy to answer the questions, understand each other, help each other!
o(o, remember the praise and, I wish you a happy and happy forever, forever and ever!)

Generally, when there is a flood, the entire power supply system will be paralyzed by a short circuit, (either the power supply bureau is cut off) Even if there is an ignition wire (phase wire) falling into the water, people will not be electrocuted in the water, because at this time, whose resistance is very small, the point is directly transmitted to the earth. Moreover, even if someone is lit at home in a flood, Hu Chun will not study it seriously after the rescue team finds the corpse, and the person who cares about the sedan chair is only to save other people or how to deal with the corpse.
The reason why the bird will not be electrocuted on the wire: because the bird is small, it only touches one wire (the bird's feet are on the same wire, and there is almost no potential difference between the two feet), its body and the wire it is standing on are equipotential, and there is no electric current passing through the body, so they will not be electrocuted. >>>More
The flood is rising, which means that the flood is rising very quickly and violently!
The Nile River is characterized by regular flooding, usually starting in May in northern Sudan, reaching its highest level in August, and gradually declining thereafter, with low levels from January to May. Although flooding occurs regularly, the amount of water and the timing of high tides vary greatly. The reason for this phenomenon is the Blue Nile and Atbara rivers, which are fed by seasonal rainstorms in the Ethiopian highlands. >>>More
This is called a misalignment knife and is limited to speed skating, which is also known as avenue speed skating. The original speed skates weren't actually dislocated, unlike short track speed skating. However, in the 90s of the 20th century, a Dutchman named Nus Corning launched a skating revolution. >>>More
Theoretically, there will be no electric shock. Because the condition of electric shock is that there is an electric current passing through the human body. According to the analysis of junior high school knowledge, the human body is regarded as a wire (the human body is a conductor), and the live wire is regarded as a power source, and there must be other conductors to connect the human body and the live wire into a closed and loop. >>>More
