Title (EN) METHOD FOR DETERMINING AN ELECTRICAL PARAMETER AND MEASUREMENT ARRANGEMENT FOR DETERMINING AN ELECTRICAL PARAMETER
(FR) PROCÉDÉ DE DÉTERMINATION D'UN PARAMÈTRE ÉLECTRIQUE ET CONFIGURATION DE MESURE PERMETTANT LA DÉTERMINATION D'UN PARAMÈTRE ÉLECTRIQUE
Abstract:
(EN) A method for determining an electrical parameter comprises charging, in parallel, a first and a second capacitor (CL1, CL2) from a common supply voltage (VL). Then, a first discharge time (t11) is determined by discharging the first capacitor (CL1). Furthermore, a second discharge time (t12) is determined by discharging the first capacitor (CL1) a second time or by discharging the second capacitor (CL2). Finally, the electrical parameter is determined from a ratio of the first and the second discharge times (t11, t12).
(FR) L'invention concerne un procédé de détermination d'un paramètre électrique comprenant la charge, en parallèle, d'un premier et d'un second condensateur (CL1, CL2) à partir d'une tension d'alimentation commune (VL). Ensuite, un premier temps de décharge (t11) est déterminé par la décharge du premier condensateur (CL1). Puis, un second temps de décharge (t12) est déterminé par la décharge du premier condensateur (CL1) une seconde fois ou par la décharge du second condensateur (CL2). Enfin, le paramètre électrique est déterminé à partir d'un rapport entre les premier et second temps de décharge (t11, t12).
