摘要：device for measuring the voltage of a power line including a capacitive dividerwith a first and second capacitors, and first (a1, a (1) and a second (a2, a'2), theamplification of the voltage at the terminals of the second capacitor, with respectdesconstantes time - of the order of hundreds of milliseconds and 2.5 to 15

milliseconds.characterized in that the lines are connected respectively to a first amplifier(i1) and a second (12) switches a logic ccntrollable (cl), the device further including acircuit (a3, red) for the absolute value of the difference (d), (e) algebraic the signalsprovided by the centre lines of the polymerase chain reactiona comparator circuit (a6)providing a circuit output control logic (cl) when the absolute value reaches a threshold.
