## 3 Electrode Station Configuration
### General Remarks
Therefore, from the application of Equation (39), it follows that the minimum distance between the frames \(ds_{\_}c\) is equal to 8.0 m. If the outline were a \"circle\", then the equal distances between successive frames would be 14.5 m (=(123 - 6 \(\times\) 6)/6). However, due to the angles of the formed polygon of Figure 14, after tests, the minimum distances between the frames are chosen equal to 12 m for frames on a straight line, and 10 m for the rest, which is, however, greater than \(ds_{\_}c\). From the respective simulation, the results of Table 6 are obtained, where the following parameters are listed:  
* The current density \(J_{\_}{st}\) with respect to the peripheral surface;
* The width \(d_{\_}{Ox}\) of the electrode station critical zone, vertical to the dam (along the Ox semi-axis), from the beginning of the axes;
* The width \(d_{\_}{Ox}\)/ of the electrode station critical zone, vertical to the dam (along the semi-axis Ox/), from the beginning of the axes;
* The length \(d_{\_}{Ox}\) of the electrode station critical zone, parallel to the dam (along the semi-axis Oy), from the beginning of the axes;
* The length \(d_{\_}{Ox}\)/ of the electrode station critical zone, parallel to the dam (along the semi-axis Oy/), from the beginning of the axes;
* The maximum electric field strength, within the region of the frame that is not operating \(E_{\_}{\_}{off}\);
* The maximum electric field strength of the array \(E_{\_}{max}\). It is pointed out that in the present cases, the boundaries of the canvas have been extended considerably (e.g., in the near-field for Korakia, it is 140 m \(\times\) 140 m, and for Stachtoroi, it is 100 m \(\times\) 120 m). Indicatively, Figure 27 shows the electric field strength and the region of developing electric field strength greater than 1.25 V/m for the most unfavourable scenario for the area of Korakia, with five frames operating (except for the second frame, under maintenance conditions), while Figure 28 presents the respective case for Stachtoroi, also with five frames operating (except for the first frame, under maintenance conditions). From the study of the results for the region of Korakia, the following emerges:* The length of the critical zone (along the Oy semi-axis) reaches up to 55.80 m (i.e., there is an inland deviation of 24.8 m) when the station is fully loaded, with the third frame not operating (the distance between the shores, which bridges the complete dam, has a length of 62 m, while, due to its arched form, it reaches 70 m). The length of the critical zone (along the Oy\({}^{/}\) semi-axis) reaches up to 62.92 m, that is, there is an inland deviation of 31.92 m when the station is fully loaded, with the sixth frame out of operation. The width of the critical zone (along the Ox\({}^{/}\) semi-axis) reaches 74.04 m. That is, there is a zero inland deviation up to 20 m when the station is fully loaded, with the second frame out of operation, due to the formed bay in Korakia (according to Figure 11). So, practically, the zone of influence extends inland laterally up to 32 m (along the yOy\({}^{/}\) axis), while along the semi-axis Ox\({}^{/}\), it is limited within the sea. * The width of the critical zone (along the Ox semi-axis) reaches up to 44.60 m when the station is fully loaded, with the fifth frame out of operation. The critical zone, outside the dam, extends by 31.6 m (with crest width of 5 m, with a suspension distance of at least 1 m, and with a distance of extreme frames on the dam along the Ox semi-axis equal to 7 m), which is better than those in all previous configurations. * The deviation in the maximum developing electric field strength of the electrode station compared to a single frame (24.84 V/m against 24.06 V/m according to Table 10 in [2]) is of the order of 3.2%, which is small and generally smaller than those in all previous configurations. * In Figure 27b, regions between the electrode frames are shown, where the electric field strength decreases significantly below 1.25 V/m.
