Which characteristic is not true for a 7200 3-phase 3-wire system?

In a 7200 3-phase 3-wire system, there is typically a focus on maintaining an efficient power supply while minimizing issues such as harmonic distortion. The primary characteristic of this type of system is its capability to operate effectively under normal three-phase conditions, making it suitable for a variety of commercial applications.

The fundamental design of a 7200 3-phase 3-wire system leads to a relatively low phase-to-ground voltage, which ensures safety and efficiency during operation. However, the creation of harmonic distortion is more associated with non-linear loads and not a feature of the system itself. In fact, a well-designed 3-phase, 3-wire system is intended to minimize harmonics, enhancing overall efficiency and power quality. Therefore, the assertion that it "provides harmonic distortion" is inaccurate, as the system itself aims to reduce such distortions.

This detail highlights why the notion of harmonic distortion is not characteristic of a well-functioning 7200 3-phase 3-wire system.
