Universal device "Universal-911" it is in exploitation of electrical engineering laboratory MT "Tulgorelektroseti" 2 years. For this time a device showed oneself from a positive side in determining the locations of damages, determination of routes and depth of bedding of cable lines of force. Wherein damage is not listened ordinary the selector of the cables (no-bottom of bedding, hindrances from other sources)" Universal-911" listened always.

Listen distance to the damages a 1,5 km and more.

A pointer indication is especially successfully executed with the irregular signal of generator.

At determination of routes of cable busses use mainly "Universal-911", on any depth of bedding the cable routing is listened and determine the depth of bedding of cables.

It am work in determination of monophase damages of cables. More practice is needed in this area. It is a sparing method of determination of monophase damages as compared to other.

A device is compact, easy-to-operate.
