A simple system for the measurement of transient horizontal electric field along the surface of lossy ground is tested in this paper. The system comprises two vertical conducting probes driven into ground, two series resistors connecting the tops of the two vertical probes, and two voltage probes. Transient horizontal electric field is evaluated as the voltage difference between the tops of the two vertical conducting probes. FDTD simulations show that the transient horizontal electric field evaluated using the measuring system agrees well with that calculated directly in the absence of the system. Furthermore, transient horizontal electric field measured in a small-scale experiment is also in good agreement with the corresponding FDTD-calculated electric field.
