发明名称 Capacitively coupled electrical ground detection circuit
摘要 An electrical ground detection circuit 10 having a first capacitor 18 and a second capacitor 20 which selectively receives a certain amount of voltage. The certain amount of voltage decreases by a certain amount during a period of time, as the capacitor 18 charges. The circuit 10 further includes a controller 16 which measures this period of time and which utilizes this measured period of time to determine whether an electrical assembly 12 is coupled to an electrically grounded member 14.
