What is one advantage of the phase-to-phase-to-ground method?

The phase-to-phase-to-ground method is advantageous primarily because it enhances the speed at which faults can be cleared due to reduced resistance between the phases. By establishing a connection between the phases and the ground, this method allows for a quicker response to fault conditions, which can lead to faster isolation of the faulted section of the system. Reduced resistance facilitates more efficient fault current flow, allowing protective devices to operate more reliably and swiftly, thereby minimizing potential damage and interruptions in service.

This method doesn't entail an increase in the risk of ground faults or remove the need for grounding. In fact, grounding is an essential part of this approach, specifically to stabilize the system and ensure safety. It also does not eliminate the complexities of grounding; instead, it strategically uses grounding principles to optimize fault detection and clearance processes.
