1. A robotic system comprising:
an electrical ground line;
a protective-earth line electrically coupled to the electrical ground line at a first point; and
a testing circuit coupled to the protective-earth line at a second point via an isolation capacitor, the testing circuit comprising a lock-in amplifier and configured to measure an impedance for the protective-earth line.
