2. Study of line transients
2.1 Telegrapher's equations
Whether a cable is supplied with voltage U to deliver a direct current i, or with voltage V a to deliver an alternating current i a , the study of its behavior in power transmission is governed by partial differential equations known as telegraphists' equations.
Consider figure 1 (by convention, the source is at abscissa x = 0). We denote by λ the linear inductance in (H · m –1 ), γ the linear capacitance in F · m –1 and r the linear resistance in Ω · m ...
