To determine the location where one of the two-wire wires

To determine the location of the cable fault, where one of the wires of the two-core cable is connected to the ground, you can use the installation, the diagram of which is shown in the figure. The installation contains a string AB along which contact K can be moved. If the galvanometer does not show deviation when contact K is at a distance of 41 cm from end B, then this indicates the location of the cable damage.

The string length is 100 cm and the cable length is 7.8 km. To solve the problem, it is necessary to use the relationship between the distance on the string and the distance on the cable. From the diagram it can be seen that the distance between points A and B on the cable and on the string are equal. Therefore, we can make a proportion: 100 cm / 7.8 km = 41 cm / x, where x is the required distance on the cable.

Solving this proportion, we get: x = (41 cm * 7.8 km) / 100 cm = 3.198 km.

Thus, the location of the cable fault is 3.198 km from the beginning of the cable.

Product name: Installation for locating faults in two-core cables

Product description:

To determine the place where one of the wires of a two-core cable has received a connection to the ground due to damage, you can use the installation, the diagram of which is shown in the figure. The installation includes a string AB and a contact K, which can be moved along the string.

Using this setup, if the galvanometer shows no deflection when terminal K is 41 cm from end B, then this indicates the location of the cable failure.

This installation is an indispensable tool for carrying out repair work on two-core cables up to 7.8 km long.

This product is a device for determining the place where one of the wires of a two-core cable has received a connection to the ground. The installation works according to the following scheme: there is a string AB along which contact K can be moved. The length of the string is 100 cm. The length of the cable on which the location of the damage needs to be determined is 7.8 km. If the galvanometer does not deflect when terminal K is 41 cm from terminal B, then the location of the cable damage can be determined. The solution to problem 31231 contains a detailed description of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer. Based on this information, the location of the cable damage can be determined.
