What voltage range typically characterizes feeders in electrical distribution?

• A. 1kV - 5kV
• B. 5kV - 10kV
• C. 12kV - 34.5kV
• D. 40kV - 60kV

Answer: (C)

Feeders in electrical distribution systems are typically characterized by voltages ranging from 12 kV to 34.5 kV. This range is essential for efficiently transmitting electrical power over medium distances while minimizing losses and maintaining system stability. The voltage level is high enough to allow for reduced current, which helps to reduce resistive losses in the conductors. At this voltage level, feeders are capable of supplying large amounts of power to substations or distribution points, facilitating the delivery of electricity to end-users. This is crucial in ensuring that the power infrastructure can accommodate the load demands of residential, commercial, and industrial customers. The other options represent either lower or higher voltage classifications. For example, voltages below 12 kV are typically associated with lower distribution lines or service drops, while voltages above 34.5 kV tend to fall into the sub-transmission or transmission category, which is used for long-distance power transmission rather than local distribution. Thus, the 12 kV to 34.5 kV range effectively supports the feeder function in an electrical distribution network.
