Case Study
HOW CAN WE SUPPORT IN THE CRITICAL MOMENTS
Maintaining a high availability is key for all power grid operators. However, putting the system back into service after a fault occurs is not always an easy task. The process usually involves the processing of electrical data, mobilization of maintenance teams, and field visual inspections.
Such a process may lead to long unavailability periods with high costs and even penalties associated with them. Therefore, a digital tool to predict, analyze, and diagnose all kinds of faults within milliseconds is essential to minimize downtime and reduce risks.

EFL DIAGRAM-CLOUD COMPUTING
EFL is designed to be very flexible in its installation and operation, it is easily adapted to the existing
facili-ties and can be integrated to existent automation networks.Data storage and computing are
thought to be on the cloud, nevertheless it is also possible to implement in a private or customer
server when there is fiber optic communication between substations.

TURNING DATA INTO VALUE
GML Enline ́s approach for fault location is to combine electrical data, including wave form records,
with Enline developed algorithms in the Digital Twin. The result is a precise fault location which can
be used by the Line operator to repair the fault and put back the line in service in the shortest
possible time.
CUSTOMER PROFILE
.Energy and Utilities: TSOs, DSOs, Power generators.
.Operation and Maintenance: Operators, maintenance companies.
Inspection companies.
.Risk Management: Insurance companies.
.Industry: Mining, metallurgicaland foundry.
OPERATION PRINCIPLE
ENLINE approach to fault location combines electrical data, including waveform registers from multiple digital recorders located at the substations, with standard and proprietary fault location methods. EFL utilizes customized fault location and cable status prediction algorithms following an innovative approach, traveling wave, time-domain, and customized methodologies ensures compliance with technical and safety requirements of the installation. As a result, it precisely locates the faults and provides accurate results, regardless of the grid topology or the fault impedance.
ENLINE SOFTWARE ADVANTAGE
The combination of these methods with our digital twin technology gives EFL a superior diagnose capacity. One of the biggest challenges in fault analysis is when the outage comes from multiple electrical and mechanical phenomena happening at almost the same time and at multiple locations. EFL is capable of dealing with these situations identifying all real and possible failure points simultaneously.
SOFTWARE REQUIREMENTS
Enline Fault Location can be easily implemented by acquiring the electrical data from the existing
automa-tion network as the input for the digital twin. EFL is also available as a complement tool of
our Enline Moni-toring System platform.
APPLICATION EXAMPLES
Among others, the software is capable to identify and diagnose the following failures, independently whether it is a transmission line with overhead, underground, or submarine cables.
Total cable rupture
Earthquake-induced damages
Partial cable rupture
Strand rupture inside the cable
Cable fall down
Discharge between cables
Wildfire impact
Atmospheric discharges
Icing related problems
Ground discharges
Corrosion
SOFTWARE APPICATION
Enline Fault Location is a standalone solution that integrates electrical data from the automation network of the asset and that requires the parametrization of the system. EFL is also available as an add-on integrated within the Enline Monitoring System platform.
COMPUTATION - CLOUD OR LOCAL SERVERS
EFL is designed to be very flexible in its installation and operation, it easily adapts to the existing
system architecture and it can be integrated into existing automation networks.
Data storage and computing can be design to take place on a cloud server or at a local server, depending on the needs of the client and provided that there is a stable and reliable internet connection at the substations.
