Network Connectivity
Network modelling and management are vital components in effective workforce and outage management. An accurate, real time, model of the network is the basis for determining which customers have lost power and for effectively communicating with them during restoration.
LeT System’s powerful network modelling tools allow for the mapping of your network infrastructure right down to the low voltage level. We work with your GIS and CIS to create the template for the network map which we then build upon using successive iterations of data acquisition.
Graphical Front-End
eRespond:model will deliver the requirements for network model improvements at the transformer, feeder and customer level.
Our advanced database application contains an extensive graphical front end that allows users to visualise and refine the network model. These proven tools are being widely used in outage management and, by a number of our clients, in direct application to meeting new regulatory requirement.
Features
- Network data can be extracted from a GIS or NMS system with relevant network connectivity data
- The customer, network devices and cables combined onto one map will provide the visual tool for linking a customer to an LV device
- This visual tool can be easily kept up to date with changes in the network topology and customer data
- The utility does not have to perform any data capturing exercise out in the field
- Mistakes in customer to LV device can be spotted visually and corrected quickly
- Customers can easily be moved from one LV device to another
- Customer to network link can be ‘cleaned’ to correct any errors by analysing faults and calls logged allowing a customer to be associated with a different device

The Connectivity Model
Utilities must be able to draw together a variety of sources of network information and maintain this effectively over time. To provide this we have developed a range of tools to support the development and maintenance of the connectivity model and the customer to network link. These include:
- Automated tools for the development of connectivity models from a variety of sources of data within the utility’s current systems
- On-line algorithms that interpret outage information to determine customer to network links
- A range of display formats to help operators interpret the network and the customer to network links, including tabular displays, map based displays, and ‘explorer-like’ browser models
This eRespond module builds a complete network model and is at the core of event and outage management activities. Network assets are modelled in terms of sites and devices. Sites define the assets’ physical location and related attributes. Devices define the asset details, e.g. type, identifier, circuit, voltage, phase, etc.
Integrated with the other eRespond modules - Contact, Outage and Workforce, or implemented separately with existing solutions the eRespond:Model solution delivers a key component to next generation Network Operations management systems.
