Live Cable Identification System (LCI)
The LCI helps in identifying energized electric power cables.
HV Mode of operation

The LCI-E PLUS transmitter is previously connected to the secondary side of a distribution transformer to identify the high voltage distribution cable located anywhere between the transformer and its source. The LCI-D Detector is used on isolated distribution cable accessories.

The equipment helps in identifying the right cable before cutting off the voltage prior to an intervention allowing thus to save time and money. It can also help in identifying a three-phase circuit by the identification of one of its conductors.

LV Mode of Operation
The LCI-E transmitter is connected at the end of a low voltage cable. It can be connected between one phase and the neutral or between phases. The transmitter draws a current whose frequency is different from that of the system or its harmonics.

Cable is identified by moving the magnetic sensor on the cable. An audible and visual indicator locates the cable connected to the transmitter.

The LCI is composed of two main parts:
A transmitter (LCI-E), which drains electric current at a specific frequency that can only be detected on the cable section between the source and the transmi t ter’s terminat ion point . Detection is even possible on highload cables.

The transmitter can be connected phase to neutral or phase to phase for better results. An automatic voltage measurement allows the transmitter to optimize the power drain.

A detector (LCI-D), which identifies the current that has been drained by the transmitter. The detector uses an external magnetic sensor. The sensor is mounted on a fiberglass stick with adjustable head.
