In this paper, a new type of portable horizontal grid earth electrode has been designed for mobile equipments. With the impulse ground measurement system, the responses to double exponential pulse current of five earth electrodes in two arrangements have been tested on soil, grassplot and cement floor respectively. After filtering and calculating, the curve of transient grounding resistance (TGR) in time domain can be gotten. And in the end, some conclusions have been drawn. The analysis of discharging capacity of horizontal grid earth electrodes in time domain has great significance in the design of mobile equipments’ earth devices.
