A hover section is displayed upon a GUI following the lapse of a hover grace period interval that is dynamically adjusted. The layer is formed from a composition having multiple reactive andor non-reactive ingredients. Therefore, even if the ground fault occurs in an output line during the load operation or a power frequency of the inverter is similar to an output frequency, the ground fault detection system and method for the inverter detect the ground fault to improve operational reliability of the inverter. In certain embodiments, the chamber is located in the headstone, and the opening may be plugged with a removable seal, or the opening may be sealed by the base of the monument. Because of a pressure difference occurring due to high-speed air current flowing along the at least one vent passage, the heated exhaust air can be positively discharged from the radiator through the at least one discharge port. The two metal silicide regions are isolated from each other by the isolation structure.
