  • Patent number: 10746807
    Abstract: Embodiments herein are directed to systems and methods for single wire precision measurement of a ground termination circuit. In some embodiments, a ground check monitoring apparatus includes a voltage source connected to a single insulated ground check wire, a pilot conductor, and a ground conductor, wherein the pilot conductor has a first resistance, and the ground conductor has a second resistance. The apparatus further includes a termination device connected between the pilot conductor and the ground conductor, and a ground conductor terminal connectable to a cable pilot wire. The apparatus may further include a ground terminal connectable with a cable ground wire, wherein voltage and current measured at the ground check terminal and the ground terminal are used to determine a ground check resistance.
