Which components typically make up a zero-sequence-type GFPE?

The correct answer identifies that zero-sequence-type Ground Fault Protection Equipment (GFPE) typically consists of three specific components: the second, third, and fifth.

Understanding the functionality of these components is essential. The first component generally relates to voltage sensing, while the fourth often pertains to circuit interruption capabilities. In contrast, the second component is crucial for detecting ground faults, the third for indicating the fault's presence within a system, and the fifth focuses on providing the necessary controls for the protective equipment.

These components collectively enable the GFPE to monitor and respond to ground faults effectively by sensing unbalanced currents that typically occur in grounded systems. This is critical in preventing equipment damage and ensuring safety. Thus, only incorporating the specific combination of components II, III, and V highlights the necessary functionalities required for effectively managing ground fault conditions, which is why this grouping is identified as the correct answer.
