Cable Identification instrument is designed to identify a special one within a group of cables during the power cable’s setting up moving maintaining and faults processing. It’s suitable for all kinds of HV & LV cables.The cable identification instrument is a special instrument developed according to the needs of the electric power industry. The cable identification instrument is used to identify a specific cable in a bundle of cables in the erection, migration, maintenance and fault handling of power cables; it has the ability to identify the cable accurately (double identification of direction and amplitude), fast, simple operation, and application Features such as wide range.
The cable identification instrument is composed of a signal generator, a receiving identification clamp and an indicator meter. The signal generator mainly generates a special pulse modulation signal, which is added to the stopped cable to be tested through the output line, and the receiving clamp is used to find the tested cable on site. For cables, when the receiving clamp detector detects a special signal applied to the cable, the meter pointer on the signal detector swings synchronously with the frequency of the applied signal. When the signal detector is used to identify the clamp signal detector, the detected signals on other cables are much smaller. And the direction is opposite, the amplitude and direction are indicated by the meter, it is easy to determine the cable under test.
