| Zusammenfassung: | A system for monitoring electrical current leakage comprises a frequency injection circuit, one or more devices, and a microprocessor. The frequency injection circuit includes an electronic oscillator providing an electrical signal to a first side of an isolation barrier. The devices are located on a second side of the isolation barrier. The microprocessor samples the electrical signal and identifies deviations in the sampled electrical signal exceeding a predetermined threshold caused by the one or more devices. The microprocessor further generates one or more alert messages based on the identified deviations in the electrical signal. |
