Abstract :
In this paper, a new type of portable horizontal grid earth electrode has been designed for mobile equipments. With FDTD method and the impulse ground measurement system, different number of earth electrodes´ responses to double exponential pulse current have been tested on grassplot. After filtering and calculating, the curve of Transient Grounding Resistance (TGR) in time domain can be gotten. The analysis of discharging capacity of horizontal grid earth electrodes in time domain has great significance in the design of mobile equipments´ earth devices.
