Cable Live Detection Device

I. Overview

The Cable Identifier is used for identifying specific cables within multiple cables during electrical cable installation, relocation, maintenance, and fault handling; it features accurate cable identification, fast operation, simple operation, and a wide range of applications.It holds significant importance in cable construction and maintenance work.EDSB-3 Live Cable IdentifierAt the transmission end, high-frequency signal encoding technology is employed to encode the transmission signal, driving a large-aperture clamp to emit an average ofHigh-frequency, high-current phase-encoded signals are utilized. A microcontroller is employed in the receiver to identify the received signals. From multiple cables several kilometers away, the receiver can identify the specific cable with the clamp by analyzing the phase characteristics of the received signals.

Section II: Key Features of the Instrument

This instrument consists of a transmitter for the cable identifier, a receiver, transmitter clamp, and receiver clamp.

When the cable grounding loop resistanceAt 50 ohms, the transmitter clamp for live cable identifier inducts a current value of no less than 4 milliamperes on the cable; the large jaw size φ150 is suitable for power cables of various cross-sectional areas.

Receiving SetThe device operates on two AA batteries with a 1.5V supply and, when paired with the receiver clamp, achieves a reception sensitivity of up to 4mA.
