## 4 Discussion  
After the assessment process of the electromagnetic field inside the considered stations, we observed that there are some values exceeding the limits of the electric field intensity, which can produce a few concerns, but there are no important issues about the magnetic field induction. When taking into consideration the magnetic field, there are some possible recommendations:  
* Reduction of the dwell time in the electromagnetic field; exposure must be allowed only during the execution of works in installations;
* Placement of warning plates in places with E \(\geq\) 10 kV/m; the plates will be painted in yellow and their inscription will be red;
* Installation of metal screens at workplaces (fixed or temporary screens), for example, when performing systematic works;
* Train personnel to know precisely the places in the electrical installations where the electric field is E \(\geq\) 10 kV/m and avoid an unjustified presence in those places;
* Interdict personnel entering or remaining in areas with E \(\geq\) 10 kV/m during meal breaks, rest or other non-working activities;
* Use of electrically insulating gloves by personnel to protect against discharging currents that appear in contact with the grounded parts, when the carrier is placed in the electric field with E \(\geq\) 10 kV/m. Other technical measures that might be considered are [1]:  
* Establish and highlight jobs with a professional risk;
* Modernize or refurbish installations;
* Replace insulation or strengthen it;
* Replace obsolete equipment;
* Provide additional signaling on all power equipment;
* Periodic control of the integrity of the earth sockets and connections;
* Measure touch and step voltages by checking the direct links to earth;
* Periodic verification of electrical equipment, supplying equipment, technical and lighting installations; perform repairs to installations according to the established programs;
* Develop check tools, special devices, kits, and protective equipment, prior to the start of work, including insulation of primary cables and equipment;
* Periodic determinations of the electric and magnetic field in the working environment, performed by authorized entities;
* Update of all working instructions and occupational safety guidelines, with provisions in accordance with the new situations after the refurbishment of the installations;
* Periodic training of staff with emphasis on workers' awareness regarding the specific risks of the jobs and the protective measures adopted;

* Ensure all measures to obtain power densities below the maximum allowed limits;
* Provide protective equipment to all employees according to the risks to their exposure risks;
* Protect persons by using reflective surfaces of the electromagnetic field, for example, any type of metal foils;
* Protect persons using screens in the workplace  
Additionally, the attenuation of the magnetic field by shielding, if possible, using a structure in the form of sheets of different materials and of different sizes, which are located between the source of the field and the protected area. This solution is generally applied to cable lines. The most commonly used magnetic field attenuation solutions are increasing the pillar height and conductive system management. The technical solution of increasing the pillar height is advantageous when the conditions in the field require only a small reduction of the level of the magnetic field, just inside the lane of the line, because outside, the reduction of the magnetic field is completely insignificant. A loop can be used to attenuate the magnetic field in the vicinity of a conducive OHL to a potential equal to or close to that of the earth. The impedance of this loop can be reduced in order to increase the current through the compensating conductor with the help of some capacitors connected in series.
