The monitoring system of water to a high tension cable, and method of water monitoring for a monitoring system of water.

摘要

"Monitoring system of water to a high tension cable, and method of water monitoring for a monitoring system of water".The invention is relating to a system of water monitoring and a method of monitoring of water for a high tension cable (CA) that includes a driver (4) and a screen (2) which surrounds the conductor.At least one first wire sensitive to water (11) extends on the screen (2) between the start of cable (CB) and the end of the cable (EC) and at least one second wire (12) is connected with the first wire (11) andXtremidade cable to form a complete circuit. A first switch unit (3) is provided between the beginning of the cable (CB) and the measuring circuit (MC).A control unit (Cu) controls the first switch unit (3) during a first time interval predetermined.A first switching condition in which the wire is sensitive to water (11) and the second wire (12) are connected to the potential of the screen.In a second time interval predetermined as follows,The control unit (Cu) controls the first switch unit (3) to a second switching condition in which the wire is sensitive to water (11) and the second wire (12) are disconnected from the potential of T.She.The measuring circuit (MC) is a measurement of the intrusion of water by performing resistance measurements or isolation, that is, measurements of voltage drop in the second time interval predetermined.Preferably the first predetermined time interval is too long, that is, 30 to 60 minutes of the second period, about 1 to 2 minutes.
