Remote digital monitoring
Secondary substations, overhead lines and cables are examples of crucial components in the distribution grid. Unfortunately, today many of these components are not monitored at all, or monitored manually by visual inspection at certain intervals. For instance cables are usually never monitored. Secondary substations are normally visually inspected once a year, hence the door could be open or the station could be affected by flooding without the knowledge of the operator. Overhead lines are inspected using helicopters and analysis of photos from inspections is a large manual job. We believe that the future distribution grid will incorporate intelligent devices for sensing, controlling, and decision making. This will play an important role in order to achieve more cost-effective operations of the future electric distribution grid. Increased remote monitoring will also, along with new tools and methodologies for decision support, lead to more optimal planning and asset management of the future system.
Digital Inspection ABB Electrification
Digital inspection involves development and testing of a modular solutions for connecting storage, inverters and sensors to ABBs smart secondary substations in order to demonstrate utility value and develop a standard product for the national and international market.
Machine learning in grid inspection
Faster and more precise grid inspection can save both time and money. Today it is common to use drones or helicopters to take pictures of the grid, and then analyse the pictures manually to look for (potential) faults.

What is the value of using sensor technology for monitoring of secondary substations?
Smart Cable Guard
Elvia is testing a new technology for faster fault location in medium-voltage cables (11-22kV). Sensors detecting partial discharge (PD) make it possible to identify weak points in the grid (e.g. weakened isolation material).
