2 show the correspondence of these tropospheric levels with the main equipotential surfaces [37; 2] = 7.5 km, [38; [infinity]] = 12 km and [38; 2] = 20 km of the fundamental field F, calibrated on the electron wavelength.

It shows that the CSIW structure has two isolated DC equipotential planes including the top plane and the bottom plane, which provide a foundation for implementing DC bias.

where n is the number of grounding elements; [[alpha].sub.mp] is the mutual resistance of GD elements with indices m and p (at m [not equal to] p) and the intrinsic resistance of elements with identical indices; [I.sub.p] is current flowing into the ground from the p-th element; [[phi].sub.G] is the potential of the grounding (equipotential).

Connect these points and obtain the approximate shape of equipotential lines as Figure 2 shows.

[H.sub.i] is the equipotential height of the nodes in the potential field.

The surge current produced by the generator flowed from the generator HV terminal to the tower top, then, through the tower construction, the LPS (Lightning Protection System), the equipotential bonding system and the earthed cable installations to the grounding system.

As a consequence, the fundamental field of the proton is complementary to that of the electron, because integer logarithms of the proton F correspond to half logarithms of the electron F and vice versa, so that the scaling factor [square root of e] connects similar equipotential surfaces of the proton field with those of the electron field in alternating sequence [8].
