Abstract
The photovoltaic installation being intended to supply an electric current (i), the method comprises the steps of measuring (e0) values representative of the electric current (i) supplied by the photovoltaic installation; adjusting (e2) a variable current jump threshold (s(ti)) according to measured values; detecting (e3) a current jump with an amplitude greater than a current jump threshold adjusted according to values measured before the jump; and detecting (e5) an electric arc based on the detection of a current jump.
