Feeders generally operate within which voltage range?

Feeders are components of electrical distribution systems that carry electricity away from substations to distribution lines. They are designed to operate at higher voltages to efficiently transport electricity over longer distances, reducing energy loss due to resistance in the conductors.

The correct voltage range for feeders, which is 2400 to 34,500 volts, is appropriate as it reflects the typical voltages used in medium voltage distribution systems. Operating within this range allows for an effective balance between minimizing losses and maintaining the capability to deliver sufficient power to downstream distribution networks and consumer loads.

In contrast, the other voltage ranges listed are more suitable for different purposes; for example, the 120 - 240 volts range is characteristic of residential and small commercial applications. Similarly, 480 - 600 volts typically pertains to industrial applications, while the 69 - 138 kV range refers to high-voltage transmission lines rather than distribution feeders. Thus, the selected answer accurately corresponds to the standard voltage levels for feeders in an electrical distribution network.
