Analysis of test circuits for measuring impulse grounding resistance

Eurocon 2013, 2013
The Paper comprises research about influential parameters on test circuits which are used for exploring impulse grounding characteristics. On the basis of conducted experimental research on horizontal grounding, using atmospheric discharge currents, amplitudes of 2.5 kA and 2.3 kA, front time of 4 μs, obtained the impulse characteristics of these ...
