Live Network LV Phase and Feeder Identifier

Taking maximum benefits from Smart Grid technology on electric distribution networks, pushes electric companies to make sure their Geographic Information System (GIS) is prepared for new challenges. 

This means GIS data has to be ready with updated information, both during deployment and full system working stages. The lack of an updated digital model of the electric system will limit the overall effectiveness of the smart grid if GIS is to be the heart of it. 

If the system does not have an exact correlation of the customer premises and electric system, any hope of automation and selfhealing of the network will be lost.

What can a Smart Grid do with an updated LV GIS connectivity data?

  • Simulate LV loads per transformer, feeder and phase (patent pending). 
  • Detect LV technical and non-technical losses, measuring delivered energy by overall transformer, or even by a single phase per LV feeder, and comparing totals with aggregate meter readings (patent pending).
  • Determine new customer's connection points, depending on network availability, without making a specific study on the field, saving therefore time and money.
  • Find critical network spots before any incident occurs.
  • Generate fictitious network traces, knowing customer's connectivity and geographic position.
  • 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.

How can GIS connectivity data be updated?

If connectivity information has not been captured recently, digitized data will most probably have an important percentage of error. The best way to have reliable information is to make a field data capturing campaign, if a good information quality is to be acquired. After gathering information massively from the field, keep GIS database constantly updated. It is crucial to design specific procedures that guarantee that as changes are made in the electrical network, they keep reflected in GIS. Otherwise data will deteriorate easily. 

Ariadna ILF6
Field working tool

ILF6 determines LV subscriber's connection link to the network, Le., identifies to which MV/LV transformer, feeder and phase is each LV customer connected to.

Main features:

  • Usable by a single operator
  • Proved efficiency in >lkm networks
  • Identifies 3 phases and up to 6 feeders
  • Works without de-energizing the grid
  • Sigma or delta secondary networks
  • PLC communicated devices
