## 3 Results of the Assessment Process
### Magnetic Field Induction Assessment Process  
The maximum measured values obtained for the 15 critical set points are presented in Table 2. All of them were performed on the 24 July 2019, during the evening (8:00-10:00 p.m., when a maximum power consumption could occur), in excellent sunny weather conditions, with no rain or fog at temperatures from 26 up to 30 \({}^{\circ}\)C, and a relative humidity from 40% up to 50%, and an air pressure of 740 mmHg.

Table 1: Maximum measured values for the electric field intensity.  
The magnetic field component depends on the load of the power system, and, by consequent, we must analyze the time variation of the magnetic field induction, especially during peak times of the day.  
Next Figures 7-14, will present the time evolution of the magnetic field induction during certain peak hours in the evening. All peak values are summarized in Table 2 around the maximum moment.
