    Abstract

    The existing of the High Voltage (HV) infrastructure creates a unique set of safety circumstances. The earthing system is one of the main elements to mitigate any unsafe conditions. Commissioning the earth grid certifies that the implemented system fulfills to the pertinent necessities. This paper endeavors to present vital information on how to perform the earth grid commissioning of an HV infrastructure. This paper will minutiae the minimum needs to guarantee the test will symbolize the actual fault case that the design was based on. A flow chart diagram is established and presented in this paper, which allows the determination of the most suitable injection route. The results of the case study are discussed, and the results are shown in this paper.
