    The main purpose of power system substation grounding system is to maintain reliable operation and provide protection for personnel and apparatus during fault condition. However, in practice, ground resistance value of substation often did not meet the required value. It can results to serious failures such as apparatus malfunction and lost of revenue. This paper presents a prototype for automatic monitoring and maintenance of those grounding system. It basically consists of a PC, Terminal Measurement Unit, Data Acquisition Unit, and Relay Board. It measures the grounding resistance and has the ability to actuate fluid sprinkler system at substation grounding system, thus improving and maintaining substation grounding system resistance to an acceptable level. This system will ultimately increase the reliability and efficiency of substation particularly when under transient over-voltage due to switching and lightning phenomena by reducing lethal ground potential rise.
