Is a neutral point and system neutral permitted for grounding purposes when using a delta-connected system over 1,000 volts?

In grounding practices for electrical systems, particularly those operating over 1,000 volts and utilizing a delta-connected configuration, the concept of a neutral point and system neutral is critical. In delta connections, there is no neutral point inherently available since the configuration connects the phases in a triangular manner without a center point.

Grounding systems rely on a solid or grounded neutral point to effectively manage fault conditions and ensure safety. In a delta-connected system, especially at higher voltages, the absence of a neutral can pose significant risks, including insufficient grounding and increased potential for electrical faults that may not be effectively cleared.

For safety and code compliance reasons, it is necessary that grounding systems, especially in high-voltage applications, have adequately defined neutral systems. Therefore, the use of a neutral point and system neutral is not permitted in delta-connected systems when the system operates above 1,000 volts, which reinforces the rationale for the answer being that it is false.
