    1. SYSTEM DESCRIPTION The purpose of this equipment is to achieve the maximum possible information regarding the low voltage network topology. This means knowing the connectivity of each accessible point of the LV network. In this document connectivity is defined as the existing connection relationship between a network point that is being analyzed, and the MV/LV transformer substation, feeder and phase that feeds it.

    5. LINE DEVICE (LD) CONNECTION 5.1. Phase to Neutral network points (STAR, B1 with neutral or B2): Connect red and blue probes the following way: o RED probe to phase cable o BLUE probe to neutral. Press (ON) to turn on the LD, it must beep and show the voltage between the red and blue probe connection points.

    5.2. Phase to Phase network points (DELTA or STAR B1 with no neutral available): Connect red and blue probes the following way: o RED probe to one phase o BLUE probe to another phase Press (ON) to turn on the LD, it must beep and show the voltage between the red and blue probe connection points.

  • Page 32: Identification Process

    6. IDENTIFICATION PROCESS 6.1. AUTO mode Press (ON) to turn on the LD, the following screen will appear: Initially the LD is in automatic mode. If it were in manual mode select automatic mode by pressing the left or right arrow button. Proceed to connect red and blue probes to the network point to be analyzed, as explained on step 5.
  • Page 33 The LD will display the voltage measurement and start searching for the signal injected by the CD. When working on Phase-Neutral mode (PH-N), and as phase and CD number data is received, it will be shown on the display: INFORMATION...
  • Page 34 When working on Phase-Phase mode (PH-PH), and as phase and CD number data is received it will be shown on the display: INFORMATION * In this example ‘PHASE: P1-P2’ will mean red probe is connected to phase 1 and blue probe to phase 2. Once the LD has received phase information it will send a signal upstream towards the transformer that will be captured by the sensor ring which corresponds to the feeder where the LD has been connected to.
  • Page 35 When the CD receives the signal transmitted by the LD it will send the corresponding feeder information to the LD. INFORMATION The LD receives the feeder code and displays it in big letters, finishing the identification process. Examples of received messages depending on network configuration: ...
  • Page 36  Phase-Phase mode: ‘PHASE: P1-P2’ will means red probe is connected to phase 1 and blue probe to phase 2.  Parallel and ringed feeders: ‘FEEDER: 4, 9’ means the customer is connected to two feeders, numbered 4 and 9. Press ENTER button if the identification process needs to be repeated.

  • Page 37: Man Mode

    6.2. MAN mode In certain cases and due to distribution network characteristics, the codes injected by CD unit on each phase may not reach the network point where the LD is connected. Then if the LD does not receive this signal, it will not send any information to the CD, resulting impossible to identify that network point in Automatic Mode.
  • Page 38 INFORMATION If the LD is transmitting for a long time in hot conditions it could happen that the device overheats. In this case “OVERTEMPERATURE” message will appear, and the LD will stop injecting the signal until it gets cooled.

  • Page 39: Tips

    7. TIPS It is important to know that the red and blue probes must be connected to the network point to identify (phase to neutral or phase to phase) throughout the whole phase and feeder identification process. The Line Device will automatically start executing the identification algorithm and in a couple of seconds, typically 5 to 15 seconds, it will display phase and feeder data.
  • Page 40 Device is connected to. In this case we recommend using the Manual Mode. It displays phase information but it doesn’t display feeder information if: There is some noise in the network which doesn’t let the feeder signal injected by the Central Device get to the network point where the Line Device is connected to.
