Why is the grounding wire placed at the top of electrical power transmission lines
Electrical power transmission towers are considered one of the most important parts of the electrical power transmission system, If we look closely at these towers, they often contain the electrical ground wire at the top, as in the picture above. What is the role of the ground wire located above the electrical power transmission lines?
The role of the ground wire in electrical power transmission lines:
The ground wire located at the top of electrical power transmission lines has several advantages and functions, which are as follows:
Lightning protection:
The ground line acts as a primary path for discharging the high electrical current resulting from electrical lightning strikes, which protects the electrical wires from burning and damage resulting from excessive electrical voltage.
Reducing electrical current losses:
Grounding wires in power transmission lines reduce electrical losses and improve system performance.
Identifying faults easily:
The landline facilitates the process of identifying faults in the wiring, thus reducing the costs of maintaining electrical networks.
Protection from electrical corrosion:
The ground wire protects the wires of electricity delivery networks from corrosion, thus prolonging their life.
Reducing electromagnetic interference:
Ground wire can be used to protect and reduce electromagnetic interference in electrical power transmission networks.
The reason for installing the ground line at the top is to increase protection from electrical lightning strikes, as it absorbs them without affecting the main electrical power transmission lines.
