Where do grounded static wires for transmission lines originate?

Grounded static wires for transmission lines primarily originate at substations. The purpose of these wires is to provide a path for static electricity to safely dissipate into the ground, minimizing the risk of electrical equipment damage and enhancing safety for maintenance personnel.

Substations play a crucial role in the electrical grid as they transform voltage levels and facilitate the distribution of electricity. They are strategically located along the transmission line infrastructure and are equipped to handle the grounding and protection measures necessary for high-voltage systems.

The other options, while involved in the electrical distribution process, do not serve as the primary point for grounding static wires. Transformers, for example, are essential for changing voltage levels but do not specifically function to manage grounded static wires in the same way that substations do. Power stations are where electricity is generated, and distribution boards are more focused on regulating the flow of electricity to different parts of the system. Thus, substations are the correct origin point for grounded static wires in this context.
