"textContent": "A power redundant system and its protection circuit is configured to have a second circuit unit receiving electricity from a first circuit unit through a power loop. An isolation switch is connected in series with the power loop. An electrical detection unit connects to the power loop to detect electrical changes and accordingly output a voltage signal to a processing unit. A first switch unit is connected in parallel to the first circuit unit and the second circuit unit. When the isolation switch is controlled to be turned off, the processing unit controls a conduction state of the first switch unit for allowing the voltage signal to change in response to the conduction state of the first switch unit. When the processing unit determines that a signal feature of the voltage signal mismatches with an isolation characteristic, the isolation switch is determined to be abnormal with an electrical leakage.",
