## 3 Electrode Station Configuration
### General Remarks
However, in the area of the non-operating frame, the corresponding electric field strength is 3.42 V/m; therefore, no issues arise (regarding safety) when maintaining the frames, provided the diver has taken the appropriate measures. * In Figure 26b, regions between the electrode frames are shown, where the electric field strength decreases significantly below 1.25 V/m. However, this does not occur in the area of the frame that is set out of operation, although it does not exceed the value of 3.42 V/m. * The deviation in the maximum developing electric field strength of the electrode station compared to a single frame (26.25 V/m against 24.06 V/m, according to Table 10 in [2]) is of the order of 9.1%, slightly higher compared to the 1 st, 3 rd, and 4 th configurations (26.09 V/m according to Table 12 of [2], 26.12 V/m according to Table 2, and 24.14 V/m according to Table 3, respectively), much higher compared to the 2 nd (19.26 V/m according to Table 1), and slightly lower compared to the 5 th (26.29 V/m according to Table 4). * The critical zone of the dam extends beyond it by 40.7 m (with a crest width of 5 m and a suspension distance of at least 1 m) along the xOx\({}^{/}\) axis (perpendicular to the dam), which is better than those in all previous configurations (1 st\(\rightarrow\)44.3 m, 2 nd\(\rightarrow\)42.7 m, 3 rd\(\rightarrow\)43.3 m, 4 th\(\rightarrow\)43.0 m), except for the 5 th, with which it is practically identical (40.6 m). * The critical zone of the dam extends beyond it by 46.78 m (i.e., 23.9 m on either side) along the yOy\({}^{/}\) axis (parallel to the dam axis) in the coastal area. Although the initially estimated required length of the assumed electrode station is 48.87 m (along the yOy\({}^{/}\) axis), the respective actual required length is 117.78 m (from the results of the superposition model according to Table 4), while the available length is only 70 m. It is practically identical to that of the fifth configuration. * The developed absolute potentials and the corresponding values of the electrode station resistance, with respect to remote earth, are quite worse (25.94 kV, 22.23 \(\Omega\)) compared to the first (22.77 kV and 19.5 \(\Omega\) according to Table 15 in [2]) and second configurations (22.48 kV and 19.26 \(\Omega\) of Table 1), slightly worse than those in the fifth configuration (25.71 kV, 22.02 \(\Omega\)), and slightly better compared to the third (26.98 kV and 23.12 \(\Omega\) of Table 2) and fourth (26.14 kV, 22.40 \(\Omega\)). * In field behaviour results, there is a similarity in the case of single-frame non-operation, between the 1 st and 6 th, the 2 nd and 5 th, as well as between the 3 rd and 4 th, through an appropriate mirroring consideration. However, when determining the absolute potentials, there is a slight difference since the integration is always carried out on the Ox semi-axis. From the study of the results for the region of Stachtoroi, the following emerges:  
* The deviation at the extremes of the array (on the yOy/ axis) reaches up to 25.56 m, and along the xOx/ axis up to 33.98 m (especially when loading five frames, except for the first or sixth). However, in the area of the non-operating frame, the respective electric field strength is 3.37 V/m; therefore, no issues arise (regarding safety) when maintaining the frames, provided the diver has taken the appropriate measures. * The deviation in the maximum developing electric field strength of the electrode station compared to a single frame (20.12 V/m against 17.96 V/m, according to Table 11 in [2]) is of the order of 12.0%, which is significant and greater than in most configurations (19.73 V/m for the first according to Table 14 in [2], 19.08 V/m for the second according to Table 1, and 20.03 V/m for the third according to Table 2), while, practically, it is identical to those in the fourth and fifth configurations (20.14 V/m according to Table 3 and 20.16 V/m according to Table 4, respectively).
