    An earthing system or known as grounding system in an electrical installation where by the grounding system connects specific parts of that installation with the Earth's conductive surface for safety and functional purposes. It is the process of transferring the immediate discharge with the aid of the low resistance wire of the electrical energy directly to the earth. It is really an important role playing in electrical system part as grounding system give protection during fault or lightning occur. In addition, grounding system also give protection for human electrical appliance and building from electrical shocks due to electrical fault or lighting occur. In this research will shows that to identify the best location to install the grounding electrode. This method is used on 10 x 10 meters which is 121 point will be investigated. The result of 0.3m, 0.6m, and 0.9m were analyzed using MATLAB software to produce profiling and shows the perfect location to install the Grounding system electrode.

    To achieve an excellent grounding system, an alternative solution was developed by using enhancement material to modify the soil surrounding the rod. These materials can effectively reduce soil resistivity and grounding resistance for a better grounding system. To achieve this goal, the fundamental part must be taken into account. In this study, the main objective is to analyze different concrete orientations as enhancement material in the grounding system. A 3-D orientation of concrete has been designed using Finite Element Method (FEM) software to analyze the performance of the electric field in the grounding system with different orientation of concrete. Every orientation of concrete had been clarified into four different cases which are full concrete, half concrete, three-quarter concrete, and a quarter concrete. From the result, full concrete is the best orientation of concrete design to be employed at the grounding site as it has a low electric field compared to the other concrete orientation.

    In this paper, the effectiveness of restricted earth fault and bias differential protection against earth fault on of transformer winding is presented. Earth fault is one of the failures that occurs on a power transformer winding. Its magnitude depends on how the neutral is connected and the location of fault. For a transformer which is connected to Neutral Earth Resistance (NER), as the fault moves towards its neutral, the magnitude of fault current decreases and the detection of fault diminishes, thus limiting percentage of winding that can be protected. To overcome this problem, restricted earth fault is employed. This paper will show that based on its principles, restricted earth fault protection is more sensitive and provide better coverage for the star winding against earth fault especially resistance earthed.

    The main purpose of the earthing is to ensure that every electrical equipment, house and human are safe when lightning strikes. Lightning phenomenon occur scan produced high voltage and current ant it can caused electrical equipment damage and life danger. Therefore, this project will analyze the behavior of the soil. The main purpose of this project was to select the soil structure and the depth of the electrode suitable for grounding system in UniMAP. Additionally, this project will also analyze the soil resistance for grounding systems using MATLAB Software. From the result it can shows the best point for located grounding rod to ensure optimum grounding system.
