How is a neutral conductor in a power system typically characterized?

A neutral conductor in a power system is primarily characterized as being grounded. Grounding the neutral conductor serves several crucial purposes, such as providing a reference point for the system voltage, enhancing safety by preventing the buildup of voltage on the neutral, and ensuring that overcurrent protection devices function correctly during fault conditions. Grounding helps to maintain the stability of the electrical system and protects both equipment and personnel from potential electrical hazards.

While insulation may be a feature of certain conductors in a system, a neutral conductor is typically grounded to ensure safety and proper functioning. Being connected to a transformer only is not a defining characteristic of the neutral; rather, neutrals can be connected to various parts of the system where needed. Elevating a conductor above ground is not typical for neutral conductors; grounded neutrals are more common in standard configurations for providing protection against voltage surges and ensuring system integrity.
