Grid connection / Protection studies
Well-set protections, before the grid reminds you
HV/MV selectivity studies, relay settings and trip analysis for wind, PV, storage and industrial substations.
Request a study
Who it is for
When a study becomes necessary
- →New connection or extension of an existing substation
- →Grid operator requirements to meet before the tests
- →Nuisance tripping or a fault whose cause remains unknown
What we do
Selectivity study
Short-circuit current calculation, coordination curves and calculation note.
Relay settings
Settings files ready to load into the substation's protection relays.
Pre-test review
Check of settings and diagrams before the grid operator's visit.
Fault diagnosis
Collecting and analysing data to find the cause of a phenomenon and propose solutions.
Example
Finding the cause of a recurring trip
From alarm logs and relay records, we reconstruct the sequence of events, identify the cause and deliver a report with concrete solutions, settings or modifications.
Substations
Wind, PV, storage, industry

Approach
Manufacturer-independent
Frequently asked questions
Before you call
Do you work with all relay manufacturers?
Yes. We are not tied to any manufacturer and adapt the settings to the installed equipment.
Do you carry out injection tests?
Tests are carried out by the installer or a specialist company; we provide the settings and attend commissioning if needed.
What do you need to get started?
The single-line diagram, the connection data from the grid operator and the transformer and relay data sheets.
A substation to protect or a fault to understand?
Send us the single-line diagram or the records, and we will get back to you quickly.
