Description

Energized MV cable identification

It works by sinking energy from a live network, by connecting a load at the LV side of an MV/LV transformer, and detecting the current that is produced at he MV side of the transformer.
The Ariadna CI-TX unit acts as the signal transmitter that sinks energy from the electric grid, producing coded current pulses, and the Ariadna CI-RX unit as the digitally tuned receiver that detects them.

Energized LV cable identification

In a similar way to MV live cable identification, it is possible to identify LV energized cables by sinking current from the network.
CI-TX transmitter is connected at the end side of the LV cable to be identified. When turned on, it starts to sink current pulses from the network, and these pulses flow from the point of injection to the LV transformer that feeds it.
With the CI-RX unit it is possible to identify LV cable path in any accessible places, like manholes, busbars, etc.

De-energized MV & LV cable identification

Through polarized frequency signal injection and detection, it is posible to positively identify de-energized cables.
Unlike live cable identification, the needed energy for generating identification signals come from Ariadna CI-TX´s rechargeable Li-Ion battery, instead of coming from the grid.
Two ways are available for injecting signals on cables, through direct connection or by using a toroidal inductive clamp.
Afterwards cables are identified by measuring produced signal´s amplitude and polarity.
