În acest articol este prezentată o metodă de calcul și un sistem de monitorizare în timp real a săgeții cablurilor liniilor aeriene de transmisie a energiei electrice, ca urmare a nevoii crescute din ultimul deceniu de a estima cu precizie valoarea acesteia. Astfel, se prezintă arhitectura hardware/software a unui astfel de sistem, care utilizează pe lângă datele geometrice ale liniei electrice, și informațiile furnizate de un senzor specializat pentru a măsura tensiunea mecanică orizontală din cablu. Pe baza ecuației catenarei se prezintă simulările numerice implementate în mediul Matlab pentru a obține valoarea săgeții cablurilor liniilor aeriene de transmisie a energiei electrice. De asemenea, se prezintă implementarea software în timp real în mediul de programare Laboratory Virtual Instrument Engineering Workbench (LabVIEW) a monitorizării stării liniilor electrice aeriene.
