Abstract

According to one embodiment, the application relates to a method for measuring the electric power propagating in a conductor by means of a flip-flop (110), which is adapted to move relative to an axle (140) and which is provided with electrodes (150a, 152a, 154a, 156a) on opposite surfaces (110a, 110b) of the flip-flop or on both sides of its axle, each of said electrodes of the flip-flop being adapted to make up part of a capacitive element (C1, C2, C3, C4). The method comprises providing a first element (C1) and a second element (C2), which are present on the opposite surfaces of the flip-flop or on both sides of its axle, with voltage signals having an effect on the flip-flop's position and being dependent on the electric power to be measured, observing by means of a measuring element (C3) a change in the flip-flop's position caused by a change in the voltage signals, and balancing the flip-flop by changing, on the basis of the change in the flip-flop's position, a voltage signal which is to be delivered to a balancing element (C4) and which is proportional to the electric power to be measured.
