3.1 Project methodology

Bonding of permanent join of metallic parts to form an electrically conductive path that ensures electrical continuity and capacity to conduct safe current. Grounding is vital to connect the metallic parts of an electrical appliances to the earth (ground) by using thick conductor wire with very low resistance for safety purposes. In other word, grounding is a connection of the neutral point of a power supply system to the earth to avoid danger during discharge of electric energy. Hazards that may occur due to failure of earthing system are electrocution, fire or explosion due to the leakage of current through undesired path and to ensure potential current carried by conductor does not rise with respect to the earth …show more content…
As this selection plays important role in effective and safe performance. The grounding however must be a metal that does not corrode easily. Grounding must be able to stabilize voltages from power source and dissipate state discharge. Hence copper is used as a standard grounding rod metal due to its high conductivity, low resistance and does not corrode easily. Copper is also able to function for a long period of time.
However, the advantages of copper made it attractive to theft as it is the top expensive metal compared to fossil fuel and it is very high demand in today’s market. The price of copper nowadays is almost equivalent to other fossil fuels and able to bet the price of other metal. Therefore, electrical and telecommunication companies find using copper as their main metal for bonding and grounding as disadvantages.
In this research, the rod used is made from copper due to its availability as the earth rod at the place where this research is conducted. Hence, additional 4 copper rod are buried at Electrical and Electronic Department open space thus the total of copper rod used are
