  • Shielded antenna for system test of a non-contact voltage detector
    Patent number: 8581609
    Abstract: A system and method of conducting a full system test on a non-contact voltage detector while simultaneously shielding the voltage detector's antenna from stray electric fields is disclosed. When a user runs the self-test, an alternating current generator capacitively couples to the antenna through an antenna shielding to detect any breaks in the antenna. The coupled signal is amplified and filtered by the voltage detector's electronics, and triggers an indicator if the voltage detector is fully operative.
    Type: Grant
