ABSTRACT:
A device and method for detecting a fault in a cable while the cable is in use. A low frequency analog test signal is added to the signal normally sent across the cable under test. Under normal operating conditions the test signal does not reflect from the load which terminates the cable. Under fault conditions, the test signal is reflected and is detected by an analog test signal detector.
