GridGIS D-twin

GridGIS D-twin, app for LV network digitalisation

 

For an efficient management of distribution networks, it is essential to have an accurate and up-to-date knowledge of the low-voltage network topology.

The GridGIS D-twin digitising app is specially developed for field work with the ILF G2 | ILF G2 Pro  devices(new versions of the Ariadna ILF 12).

Developed by Ariadna Grid (our technical partner), it automatically stores the results of the correspondence between the meter and the Secondary Substation, with the feeder and phase number to which it is connected.

Through this application the data capture is displayed on a map of the work area, quickly and easily.

Main Features

 

  • Secondary Substation (SS) asset register: SS identifier, transformer, LV panel, feeder numbers, type of MV and LV cables, MV switchgear, etc.
  • Recording of the device configuration: Central Unit code, correspondence between feeder number and Rogowski sensor input number…
  • Topology/CONNECTIVITY: loging of the energy meter identification with the Line Unit: Secondary Substation – feeder – phase + date – time + operator.
  • Photo of each identified asset
  • GPS geolocalization  of each identified asset: SS, meter boxes, pole, meter…
  • Track work progress
  • Bluetooth connection
  • Export/Import in files compatible with GIS tools: GeoJSON, KMZ and Shapefile
  • Data integration with the utility’s GIS system

ILF G2 Pro

Phase and feeder identifier

Advanced version of the ILF G2 device, specially designed for big mapping and digitising campaigns of the distribution network, helping to reduce the duration of the campaign and providing great cost savings.

Thanks to its digitisation app GridGIS D-twin (developed by Ariadna Grid), the ILF G2Pro is able to add, edit and store over the same map, the location and connection of all consumers in the Low Voltage distribution network. It identifies and digitises, with total reliability, to which Secondary Substation, Low Voltage panel, outgoing feeder and phase each of the meters/consumers in the network are connected.

Main features

Features added to the ILF G2

  • Identification of the 3 phases and up to 12 feeders of a LV panel, possibility of having several devices in parallel if there are more feeders.
  • In live networks.
  • Designed for big network mapping campaigns, up to 99 devices can work at the same time.
  • Adapted to different types of distribution networks: cascade or/and in parallel mode, allowing to know the connectivity of the consumer with respect to each intermediate element of the distribution network (feeder pillars).
  • Integrated Bluetooth for automatic data transfer to the digitisation app (compatible with GIS systems).
  • GridGIS D-twin digitising app licence included.

LV Transformer Supervisor

The LV transformer supervisor allows the status of the LV transformer in the Secondary Substation to be monitored. Compatible with any type of transformer, it has a three-phase voltage input and one or two three-phase current inputs for measuring electrical parameters.

Equipped with several communication ports, it allows complete monitoring of the transformer’s electrical parameters, including temperature measurement in the advanced version of the device. Its easy and intuitive user interface allows to quickly check its correct installation and operation.

 

Applications

  • Transformer supervisor in the LV output: monitoring up to 2 different outputs. For indoor or outdoor transformers (on a pole)
  • Feeder supervisor in the Secondary Substation: LV panel supply feeder or LV outgoing feeder
  • Monitoring of any intermediate element of the LV network: feeder pillar, main circuit breaker protection box…
  • LV network remote monitoring. Device compatible with a 4G router
  • Measurement of harmonics in voltage and current and THD (Total Harmonic Distortion), up to n=40 (*)
  • Internal algorithm for estimating transformer oil temperature. This data can be used to know the transformer status, its overload level and its aging (*)
