According to relevant studies, power transmission and transformation facilities do not generate electromagnetic radiation, and their main environmental impacts are power frequency electric field, power frequency magnetic field and low frequency noise. Power frequency electric field strength, power frequency magnetic induction intensity and noise will decrease with the increase of distance. So, will these effects cause harm to the human body?
In fact, relevant international scientific research institutions have already confirmed through research that the low power frequency electromagnetic field will not be harmful to human health or cause human diseases. And China has also formulated relevant standards to strictly control the power frequency electric field intensity limit of 4 kV/m, and the power frequency magnetic induction intensity is 100 micro Tesla. After years of monitoring by the ecological environment department of the power transmission and transformation facilities in operation in Fuzhou, the measured values of all measurement points can meet this standard. For the power transmission and transformation facilities newly put into operation every year, there will also be special personnel to carry out acceptance monitoring, so everyone can rest assured.
In addition to the power frequency electromagnetic field, there is also a certain noise impact around the substation. This is mainly due to the use of 50 Hz alternating current in my country's power grid, which will be accompanied by low-frequency noise. Power supply companies and ecological and environmental departments have attached great importance to this, and have taken a series of measures such as theoretical prediction, noise reduction and sound insulation to ensure that the acoustic environment around the substation can meet the relevant environmental standard limits. If some substations that have been in operation for a long time exceed the standard, noise reduction measures will also be taken as soon as possible to ensure that the excessive noise will not affect the lives of the people.
