How can you determine if a cable is damaged, how can you find it?
How can you determine if a cable is damaged, how can you find it? Visually invisible, the insulation seems intact.he himself thought about the task of the construction task. I did not think of anything better how to cut the cable into small pieces and check them with an ohm meter or something like that. and when the broken segment is found, it is sawn into pieces and then it looks and then the piece that does not pass the current is thrown away. here.
1. Simply bend the cable - the damaged area will bend at an acute angle.
2. If the cable is thick enough, and the insulation is soft enough, you can put a needle on the ends of the tester wires and pierce the insulation and touch the cable to find the approximate break point.
3. Buy a special device to determine the location of damage (rupture).
4. If the cable is NOT rare, and NOT expensive, then you should save your time and nerves and just buy a NEW one.
What cable, power, signal (digital, analog), optical? What happened in detail. Need more information!
Yes, you need to know which cable is
just a
simple tester, or if there is a weak current, then this is such an ancient garbage)
and if you need to determine the location of damage over a long length, then ..

With an ohmmeter or a probe with a light bulb, you find a broken core, then you start bending the cable in steps of a centimeter, where the arrow jumps / the lamp flashes, there is a break. This is if we are not talking about a power cable for a dofigalion of squares, which must be bent with an excavator.
If it is the sheath to check the cable, then for this you need specialized equipment such as baur shirla https://npp-tp.ru/products/17045/17100/shirla-avtomaticheskaya-sistema-dlya-ispyitaniya-obolochek-kabelej-i-opredeleniya- mestopolozheniya-povrezhdenij.html. Well, the very continuity of the cable with a multimeter can be arranged.
Before starting the rewinding of submersible pumps, we check the cable as follows;
We fill the bathtub with water, lower the wire into the water so that it is completely in the water, do not lower the beginning and end into the water, we hook up a megohmmeter to one end and twist it, then we discharge the other end into the water (so we understand that the insulation is intact). If the insulation is broken, the wire shoots in the water, and the ohmmeter drops to 0.
