A capacitive voltage sensor apparatus including an electrically insulating body, an elongated conductor embedded at least partially in the insulating body, a first floating sensor electrode embedded in the insulating body and capacitively coupled to the elongated conductor and configured to provide a first output representing the voltage of the elongated conductor, and a second floating sensor electrode embedded in the insulating body and capacitively coupled to the elongated conductor and configured both to provide a second output representing the voltage of the elongated conductor and to shield the first floating sensor electrode from electric fields that may originate from sources external to the capacitive voltage sensor apparatus. A capacitor may be embedded in the insulating body and electrically connected with the first electrical sensor to form a capacitive voltage divider that provides the first output. The first output may provide a precision LPVT output and the second output may provide an output for a voltage presence indication system or voltage detection indication system.
