Conclusion
Transportation and distribution networks

EHV and HV networks, with tens of thousands of kilometers of links and hundreds of substations scattered across the country, are susceptible to internal faults or external aggression, against which they need to be protected.

Protection systems must be designed to protect not only the structures themselves, but also the entire power system, whose equilibrium is fragile.

The need arises for individual protection systems whose performance in terms of speed, reliability and selectivity is determined by the needs of the networks, which must also be combined to form a genuine protection plan for the system as a whole.

This implies the use of high-performance equipment, in terms of both function and reliability, employing the most modern measurement techniques, coupled with no less high-performance, modern transmission...
