About Cable Identifiers
A Cable Identifier is utilised by Electrical Transmission Engineers and is a toolbox staple when reliable high-voltage cable identification is required. Cable identifiers can safely identify a dead (or de-energised) primary cable within a group of energised or de-energised cables. They can also identify cable lengths and phases, and live secondary cables, including neutrals (Cable Identifier model dependent).
The absolutely clear and unambiguous identification of a power cable before cutting or jointing is of great importance for safety. Any mistakes can result in significant property damage, personal injury or even death of the cable technician. Additionally, an incident will often cause unplanned in-service outages for connected customers (Cable Identifier model dependent).
Cable Identifiers often capture the following parameters to distinguish the useful signal from interference:
- Impulse shape

Megger CI/LCI is a good example of a Cable Identifier
Megger CI/LCI is a reliable cable identifier for de-energised and energised (live) cables!
This generator CI TX transmits single pulses with a peak current of up to 100 A. The current flow of the impulses causes an electromagnetic field with a well-defined polarity around the connected power cable, which gets picked up of the receiver CI RX, and which is automatically synchronised and displayed on the LED indicator scale. The only adjustment is the displayed signal sensitivity.
The CI/LCI Cable Identifiers have been developed to make the task of cable identification and selection considerably safer and easier.
The system consists of a generator unit that sends defined impulses, and a receiver unit. This receiver CI RX is connected via a flex clamp (AZF 150-CI or AZF 250-CI) in order to decouple the transmitter signal sent by the generator into the cable that is supposed to be identified.
