What is the function of earthing systems in electricity?

The function of earthing systems in electricity is primarily to protect against electric shock and equipment damage. An earthing system provides a safe pathway for electric current to flow into the ground in the event of a fault, such as short circuits or equipment failures. By directing the excess electricity away from individuals and sensitive equipment, earthing systems significantly reduce the risk of electric shock to people and lower the chances of fire or equipment failure due to overvoltage or surges.

This protective measure is vital in ensuring safety in electrical installations, as it prevents dangerous build-up of voltages that could lead to hazardous situations. Additionally, grounding can help stabilize the electrical system by providing a reference point for voltage that can enhance overall system safety.

Although options related to distributing electricity, enhancing power efficiency, or stabilizing voltage levels mention important aspects of electrical systems, they do not address the core protective role that earthing serves, which is crucial for ensuring safety and mitigating risks associated with electrical faults.
