Megger CI LCI Cable Identification Set - For Dead and Live Cables up to 440V
Cable identification on de-energised cables with the CI Set
Clear identification of a cable before it is cut or fitted is a task with absolute relevance to safety. Any mistakes here can have fatal consequences for the cable fitter and cause outages for the connected customers. The CI cable identification system has been designed for even simpler, safer working. The system consists of the current pulse generator CI TX and the receiver CI RX. This receiver is permanently connected with a 120 mm flex converter for decoupling the identification signal. Pulse generator CI TX generates sawtooth pulses up to a peak current of 100 A and sends them to the cable being identified. This current causes an electromagnetic field around the cable which is registered with the flex converter of the receiver CI RX, automatically synchronised and displayed on the LED scale.
The only possible adjustment is to vary the strength of deflection in the display. A special software function controls and verifies all parameters of the registered pulse. The directional clamp together with parameter monitoring by the receiver warrants very safe readings regardless of any interference. The generator unit has a battery runtime of more than 4 hours to make the system extraordinarily flexible in use. CI TX which runs on mains power in the standard version is also available with lead cell batteries and an integrated battery charger as an option. Work in low-voltage cable networks is increasingly being carried out under live voltage (AUL). This demands unequivocal identification of the correct cable, which naturally has to be possible without switching off the mains voltage.
Cable identification on energised cables with the LCI Set
Pulse generator LCI TX (Live Cable Identifier) is connected by a protective conductor lead with the 115V/230 V AC power supply. The feed transformer is subject to power withdrawal of approx. 80 A by the device at intervals of approx. 2 seconds. This results in a pulse current on the section of cable: the current is received by the reading clamp and is thus used for reliable identification of this section of cable (not suitable for IT networks!). This guarantees correct connection to safety sockets. A safety clamp with integrated fuse is available for coupling to public distribution networks. The small dimensions of both pulse generators permit trouble free use in switchboards.
