Abstract

PURPOSE: To judge the disconnected section easily and quickly by beforehand inserting fixed resistances at every section in a circuit used for monitoring of the commucation cable to be monitored and measuring the combined resistance value examined from one end of said monitoring circuit.
CONSTITUTION: Fixed resistances 2 are inserted at every fixed section to a monitoring circuit 3 provided in the cable to be monitored. Beforehand, the combined resistance from a measuring terminal 1 up to each inserted resistance 2 is measured. When the monitoring circuit is disconnected on the way owing to a certain cause, the combined resistance value in the lower direction from the measuring terminal 1 is measured and is compared with the resistance value having beforehand been measured, whereby the distance up to the disconnected section is estimated.
