1 Ariadna Instruments Power cable identifier & LV live network phase and feeder identifier

2 Cable identifiers

3 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 deenergized cables. Ariadna IC1G: Identifies low voltage cables

4 Cable identifiers Ariadna CI

5 Cable identifiers 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).

6 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).

7 Cable identifiers Low Voltage

8 Cable identifiers Medium Voltage

9 Cable identifiers No Voltage

10 Cable identifiers No Voltage CI- RX CI- TX

11 Cable identifiers: IC1G Ariadna IC1G

12 Cable identifiers: IC1G 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

13 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.

15 Low voltage phase and feeder identifiers

16 Low Voltage Connectivity, transformer, phase y feeder What is the L.V. connectivity? The link between L.V. electricity meter M.V./L.V. Transformer, phase and feeder

17 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.

18 Live network LV line phase and feeder identifier Target Customers Main Objectives GIS, Cartography departments of Electrical Utilities Technical and non-technical losses departaments of Electrical Utilities

19 Low voltage phase and feeder identifiers Ariadna ILF-12

20 Low voltage phase and feeder identifiers 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

21 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..

23 Low voltage phase and feeder identifiers Ariadna ILF-6

24 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

25 Low voltage phase and feeder identifiers Ariadna ILF6 Allows us to obtain data connectivity customers connected to transformers up to 6 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.. Lets work on single-phase 3-wire output (2-phase and neutral).
