Bashkirenergo Tests Intelligent Fault Location Technology for 10kV Distribution Networks
Digital technologies are set to improve fault detection across Bashkirenergo's medium-voltage distribution grid. The utility has begun testing a specialized fault location module developed by Monitor Electric.
Initial field trials are already underway at an operating section of the Northern Distribution District within Bashkirenergo's Ufa Urban Electric Networks division. The system is built around the FLOC (Fault Location) module developed by Monitor Electric for the SK-11 hardware and software platform. The module automatically identifies damaged sections of a distribution network following a single-phase short circuit, one of the most common fault types affecting overhead medium-voltage power lines.
The FLOC module performs a comprehensive analysis of data transmitted by fault indicators and sensors installed along power lines. It verifies sensor health, filters out false activations, and then uses a dedicated algorithm to pinpoint the faulted section of the network. Consumers can subsequently be transferred to alternative power sources while repairs are carried out.
That approach not only minimizes outage duration but also streamlines repair operations. Instead of spending valuable time patrolling long sections of distribution lines to locate a fault, maintenance crews can travel directly to the section identified by the system.
From Pilot Project to Grid Standard
Once testing is complete, Bashkirenergo will decide whether to deploy additional FLOC modules across other parts of its distribution network.
Over the longer term, the objective extends beyond introducing another layer of distribution automation. The technology is intended to become part of a broader digital grid management architecture. Integrating FLOC with dispatch systems and remotely operated switching equipment would make it possible to isolate a faulted section automatically and, once the short circuit has been cleared, restore it to service without manual intervention.
The technology has particularly strong potential for long 6-10kV distribution lines running through remote areas with challenging terrain, where locating damaged sections quickly remains difficult.
Standardization Drives Digital Grid Development
The Bashkirenergo pilot reflects a broader trend toward automating operational processes across Russia's electric power sector.In 2022, the Rosseti Group incorporated digital infrastructure and telecontrol technologies into its technical policy program as the foundation for remote operation of grid assets. Industry-wide technical requirements for overhead line fault indicators were approved in 2023.
Systems similar to the one being tested by Bashkirenergo are also being deployed by other distribution network operators. In March 2026, Rosseti Lenenergo announced the first Russian deployment of the intelligent AutoFLISR automatic service restoration system. Meanwhile, Russia's Ministry of Energy has emphasized that one of its priorities is to standardize the various digital technologies being introduced across the country's electric power industry.
From Fault Detection to Autonomous Grid Control
The Bashkirenergo project represents an important step toward building intelligent distribution networks. If the trials are successful, the utility will gain a tool capable of reducing outage restoration times while lowering the operational burden on maintenance crews.
Over time, wider deployment of digital technologies could enable utilities to move beyond fault diagnosis toward automated control of entire distribution networks. In line with the Ministry of Energy's strategy, systems of this kind could eventually become standard components of digitally managed distribution districts throughout Russia.
