Explanation: A VFD’s “ground fault protection” feature is designed to protect the VFD, the electric motor, and the system as a whole from damage caused by ground faults. This feature monitors the electrical system for signs of a ground fault, such as an imbalance in the current flowing through the system, and will shut down the system if a ground fault is detected. This feature is an important safety feature that can help to prevent electrical fires and other hazards caused by ground faults.
