Abstract
Disclosed are apparatus, methods, and systems for the monitoring of grounding components in an electrical system. Methods of monitoring grounding components comprise a signal or plurality of signals imposed on a ground loop circuit by a first inductive element, a second inductive element which receives the signal(s), and circuitry which compares changes in the imposed signal(s) to a baseline to calculate impedance. Active monitoring of impedance enables contractors to ensure installation of a grounding system was performed correctly, and allows a user to track changes in impedance over the life of the electrical system such that, if an impedance threshold is reached, appropriate action may be taken.
