TRANSCRIPT
Cable identifiers
There are situations where it is necessary a correctly identification the
distribution cables, such as in fault repairing, executing splices or branches,
conducting campaigns client connectivity, etc.
Cut the wrong cable may have the following consequences:
- Danger of accidents.
- Cut in electricity supply.
These equipments are very helpfulf or the maintenance department because
they allow us to identify a particular cable before acting on it…
Equipments:
Ariadna CI: Identifies the cable in medium and low voltage, and de-
energized cables.
Ariadna IC1G: Identifies low voltage cables
Ariadna CI FEATURES
Identifies:
- Cables without voltage.
- Cables with voltage, medium and low voltage.
Works on:
- Single-phase cables.
-Cables of 3-phase or 3-phase + neutral.
The injection signal is produced by:
- Direct connection to wires.
- Signal induced by an inductive clamp (optional).
- Detects the amplitude and polarity of an active signal.
- Maximum cable distance> 10 km (direct connection).
- The transmitter's rechargeable Li-ion battery lasts 24h in the level 2 of
transmission (has 4 levels).
Cable identifiers
Ariadna CI
•Interesting for electrical maintenance departments and contractors
•Identifies medium voltage cables without disconnecting from the
network. The equipment handling is always done at low voltage.
•Identifies unipolar or tripolar leads
•The transmitter TX is connected to the network and the signal travels
upstream directly to the transformer (low voltage) or to the substation
(medium voltage).
Cable identifiers
IC1G FEATURES
Identifies BT cables without power outage.
Valid for LOW VOLTAGE distribution cables up to 250V (50 or 60 Hz).
Identifies unipolar or multipolar cables.
The algorithm used runs continuously, and in few seconds a positive
identification of the analyzed cable is done.
Easy operation because of automatic synchronization between
transmitter and receiver.
On the graphic display of the transmitter TX, shown the voltage at the
point of injection, and in the receiver RX, intensity and polarity of the
signal detected
Cable identifiers: IC1G
Ariadna IC1G
•Interesting for the departments of low voltage electrical maintenance
•Only identifies low voltage cables connected to the network
•The transmission unit is very compact (like the line unit)
•The transmitting unit TX is connected to the network and the signal travels
upstream toward the center of transformation.
Cable identifiers: IC1G
What is the L.V. connectivity? The link between…
L.V. electricity meter M.V./L.V. Transformer, phase and feeder
Low Voltage Connectivity, transformer, phase y feeder
Why LV connectivity?
• Simulate LV loads per transformer, feeder and phase. Load Balance
• Detect LV technical and non-technical losses
• Determine new customer’s connection points without making a specific study on the
field
• Find critical network spots before any incident occurs
• Generate fictitious network traces
• Spot network failure elements, by grouping customer’s incidents by connectivity link
• Determine which customers to be notified before any programmed supply interrupt is
made
• Identify exactly which customers need to be compensated due to power supply
incidents.

ILF12 FEATURES
Works in service, without de-energizing the feeder.
Three phases and up to 12 feeders can be identified in few seconds.
It can be encoded the central unit's number to work with different
equipments simultaneously
Proved efficiency on line distances greater than 1 km.
Central and Line Unit communicate with each other by means of coded
messages through the distribution network. This way the use of radio or
other communication extra equipment is avoided.
Operational for all kind of Low Voltage network configurations, Delta,
Triangle (no neutral) and up to 440 Vac between phases, 50 or 60 Hz, with
coupled and/or ringed feeders.
A single operator can easily use it
Low voltage phase and feeder identifiers
Ariadna ILF12
Allows us to obtain data connectivity customers connected to large
transformers up to 12 lines.
For more number of lines, we can work with several central units in
parallel.
The central unit is placed in the center of transformation, and operator
captures customer data with the line unit downstream in the network..
Low voltage phase and feeder identifiers
ILF6 FEATURES
Works on live networks, without de-energizing the line
Three phases and up to 6 feeders can be identified in few seconds
Proved efficiency in lines of more than 1 km
Central and Line Unit communicate with each other by means of coded
messages through the distribution network. This way the use of radio or other
communication extra equipment is avoided
Usable by a single operator
Operational for all kinds of Low Voltage network configurations, up to 480 V
between phases, 50 or 60 Hz, with coupled and/or ringed lines
“Plug and Play”. Contains what is needed to start working, without any
additional adjustment or programming
