... lightning strikes to the end of the grounding wire line in case of open-ended grounding wire or the end of the grounding wire connecting with the grounding system impedance of substation (Z1): ... From the above analysis, we have a method to calculate the current value passing through the grounding system impedance of substation when lightning strikes at any point on the grounding wire of ... Determine the Thevenin impedance (seeing from the position that lightning strikes to the substations) in case of grounding wire line connecting with grounding system of these substations, with the...

He thought that inertial forces were just gravitational ... equivalent to central gravitational field by tidal forces so that the principle of equivalence holds only for small regions of space. We also find that when the system of frame moves with velocity...
