Abstract

In this paper, we measure the ground resistance of solar power, would like to propose a standardized measurement techniques. Therefore, we have studied the principles and domestic, measurement techniques that have been applied to the outside of the ground measurements. Investigate the application problem in the field, it is attempted to secure a variety of measurement techniques. And discuss the ground to date, actually ground noise signal and ground resistance in the field, which has been in operation, such as the circuit of the wiring configuration were measured and analyzed. Based on the results of the analysis to study the grounding system capable of removing a noise signal. Field installation of the grounding system can be constructed in consideration of the connection position with the internal wiring, to confirm the performance by comparing the construction. It was also re-measured ground noise signal during equipment operational states in order to confirm the effect of improving the post-construction. By comparing the measurement result of the improvement before and after the noise signal, and finally we check the performance of the protective equipment.
