摘要： A method of evaluating the accuracy of an electricity meter, the method comprising: a preliminary stage comprising a step of acquiring first measurements of a first electrical magnitude, and a step of detecting a period of stability; a test stage comprising a step of injecting a test current into a conductor of the electricity meter, and a step of acquiring at least one second measurement of the first electrical magnitude; an evaluation stage comprising a step of comparing the second measurement of the first electrical magnitude with the sum of a first stability value representative of the first electrical magnitude during the period of stability plus a predefined value corresponding to the expected increase in the first electrical magnitude due to injecting the test current, and a step of evaluating the accuracy of the meter from said comparison.

摘要： An electricity meter includes at least one phase conductor and a neutral conductor, an internal cut-off device includes at least one phase cut-off member connected in series with the phase conductor, and at least one detector circuit for acting when the internal cut-off device is open to detect whether a circuit breaker of the installation is open or closed. The electricity meter includes coupling components connected, downstream from the internal cut-off device, to an injection conductor selected from the phase conductor and the neutral conductor, and an injection component arranged to apply a reference voltage to the injection conductor via the coupling capacitor; and connection components connected to a measurement conductor selected from the phase conductor and the neutral conductor, and a measurement component arranged to measure a measurement voltage across the terminals of one of the connection components, the measurement voltage being representative of an impedance of the installation.
