Is the substation behind the yard bad for feng shui?

The high voltage of the substation will form electromagnetic waves, which will definitely affect people nearby. I wonder if it will be close to your home. Too close is definitely not good. This is called electromagnetic evil spirit in geomantic omen. After a long time, the mental state of the family will be affected, and the temper will be impulsive, the spirit will not be concentrated, and lotus flowers will easily appear and accidents will easily occur. Suggest hanging copper gourd in the backyard to solve them.
