The role of live cable identification instrument

　　The live cable identification instrument is used to identify a specific cable in a bundle of cables during the installation, migration, maintenance and troubleshooting of power cables. It has the characteristics of accurate and fast cable identification, simple operation and wide application range. It is an indispensable detection instrument in cable construction and maintenance work. The live/de-energized cable identification instrument uses single-chip microcomputer technology to encode and power drive the transmission signal at the transmitting end, and drives the large-caliber caliper to couple the signal to the live cable. The single-chip microcomputer in the receiver decodes and phase identifies the received phase-coded signal. The target cable is identified from a large bundle of other cables based on the uniqueness of the signal phase characteristics on the target cable. It is a light, compact, lithium battery-powered portable instrument. It is suitable for various types of high and low voltage power cables.

　　The live cable identification instrument consists of a cable identification transmitter, a cable identification receiver, a transmitting clamp, a receiving clamp and an output signal connection line. It has a high-power current pulse output; the on-site receiving signal has clear characteristics, is light and flexible, has high sensitivity, and can effectively suppress on-site power frequency interference; the judgment is accurate and fast; the protection circuit is reliable, and it is not afraid of output short circuit; the large jaw ф125 is suitable for power cables of various cross-sectional areas; it has a high-power isolation transformer inside, and the operator does not have any direct electrical contact with the mains. It greatly guarantees personal safety. When identifying live cables, it is not necessary to disconnect the connection between the two ends of each cable and the power distribution equipment. Online identification can be performed when the cable is in a live state, which improves the efficiency of identification and greatly reduces the direct and indirect economic losses caused by power outages.

　　Product features of live cable identification instrument

　　The energized identification and de-energized identification functions are combined into one, which is not only suitable for the identification and judgment of out-of-service cables, but also suitable for the identification and judgment of energized cables. The operation is extremely simple and the use is very convenient.

　　The instrument is powered by a lithium battery and can work continuously for 3 to 5 hours, making it suitable for passive field use.

　　With optical power monitoring function, supporting all types of optical fiber interfaces

　　This live cable identification instrument is different from conventional identification instruments. It uses the latest communication technology. The single-chip microcomputer technology is used at the transmitting end to encode and power drive the transmission signal and couple the signal to the cable. The single-chip microcomputer in the receiver decodes and phase-identifies the received phase-coded signal. The target cable is identified from a large bundle of cables based on the uniqueness of the signal phase characteristics on the target cable. Therefore, the working performance is reliable, and it can accurately identify ultra-long cables. It is suitable for various types of high and low voltage power cables.
