Abstract
A robotic system may include an electrical ground line and a protective earth line electrically coupled to the electrical ground line. The robotic system may also include a testing circuit coupled to the protective-earth line via an isolation capacitor. The testing circuit may include a lock-in amplifier and may be configured to measure an impedance for the protective-earth line through the isolation capacitor. Methods for testing or monitoring protective-earth lines are also disclosed herein.
