El método comprende: tomar unas señales de la red de baja tensión; adaptarlas para su posterior tratamiento digital; tratarlas en un convertidor analógico a digital; procesarlas digitalmente en un microcontrolador para calcular el valor eficaz de la señal fase-neutro y registrarlo en una memoria no volátil; comparar la amplitud de las señales con una referencia que si es superada ordena al microcontrolador registre una ventana temporal descriptiva de la señal que contiene la sobretensión transitoria; y adjudicar un sello temporal mediante un reloj del sistema a todos los valores o eventos que se registran en cualquiera de las memorias.Method and system for measuring harmful electrical disturbances for electrical or electronic equipment connected to a low voltage network. # The present invention relates to a method and system for measuring harmful electrical disturbances for electrical or electronic receiver equipment connected to A low voltage network. The method comprises: taking signals from the low voltage network; adapt them for later digital processing; treat them in an analog to digital converter; process them digitally in a microcontroller to calculate the effective value of the phase-neutral signal and record it in a non-volatile memory; compare the amplitude of the signals with a reference that, if exceeded, instructs the microcontroller to register a descriptive time window of the signal containing the transient overvoltage; and assign a temporary stamp by means of a system clock to all the values or events that are recorded in any of the memories.

Reivindicaciones 1-5 El documento D01 es el documento del estado de la técnica más próximo a la invención reivindicada. En él se describe un método para la medición de perturbaciones eléctricas dañinas para equipos conectados a una red de baja tensión, con los siguientes pasos: tomar dos señales, adaptarlas mediante un amplificador diferencial y un filtro de altas frecuencias. Posteriormente se digitalizan las señales anteriores mediante un convertidor analógico digital y se compara la señal con unos umbrales establecidos previamente. La diferencia con la invención reivindicada es que el documento D01 adapta la señal mediante un amplificador diferencial y la conversión a binario, mientras que la invención reivindicada utiliza un divisor de tensión y la adicción de un nivel de continua. Por otro lado, el documento D02 se refiere a un método de medida de corriente, con los siguientes pasos: tomar la señal de la red, adaptar la señal, digitalizarla mediante un convertido analógico digital, reconstruir la señal correspondiente en un microcontrolador, comparar la amplitud de la señal mediante circuitos comparadores con unos umbrales preestablecidos previamente y cuando se superan estos umbrales se registran un determinado número de muestras de la señal en una memoria. La diferencia con la invención reivindicada es que no se adjudica un sello temporal a los valores registrados. Por último, el documento D03, referido a la monitorización de las condiciones de una línea eléctrica, adjudica un sello temporal a los valores registrados cuando la línea está en falta. No obstante, los documentos recuperados no describen un método como el de la invención reivindicada ni de los que se pueda deducir este, por si solos o en combinación. Por tanto, se considera que la invención de las reivindicaciones 1-5 son nuevas y tienen actividad inventiva, según lo indicado en los artículos 6 y 8 de la Ley de Patentes 11/1986, de 20 de marzo. -Reivindicación 6 El documento D04 describe un sistema para la medición de perturbaciones eléctricas dañinas para equipos, que comprende: un módulo de alimentación, un módulo de preparación de medidas, un puerto de comunicaciones, un reloj en tiempo real y un microcontrolador. Por tanto, el documento D04 afecta a la novedad de la reivindicación 6, según el artículo 6 de la Ley de Patentes 11/1986, de 20 de marzo. -Reivindicaciones 7-10 Los detalles estructurales constructivos son meras opciones de diseño que no producen ningún efecto técnico adicional con respecto al documento D04. Por tanto, el documento D04 afecta a la actividad inventiva de las reivindicaciones 7-10, según el artículo 8 de la Ley de Patentes 11/1986, de 20 de marzo.Claims 1-5 Document D01 is the state of the art document closest to the claimed invention. It describes a method for measuring harmful electrical disturbances for equipment connected to a low voltage network, with the following steps: take two signals, adapt them using a differential amplifier and a high frequency filter. Subsequently, the previous signals are digitized by means of a digital analog converter and the signal is compared with previously established thresholds. The difference with the claimed invention is that document D01 adapts the signal by means of a differential amplifier and the conversion to binary, while the claimed invention uses a voltage divider and the addition of a continuous level. On the other hand, document D02 refers to a method of measuring current, with the following steps: take the signal from the network, adapt the signal, digitize it by means of a digital analog convert, reconstruct the corresponding signal in a microcontroller, compare the amplitude of the signal by means of comparator circuits with pre-established thresholds and when these thresholds are exceeded, a certain number of samples of the signal are recorded in a memory. The difference with the claimed invention is that a temporary stamp is not awarded to the registered values. Finally, document D03, referring to the monitoring of the conditions of an electric line, awards a temporary stamp to the values recorded when the line is missing. However, the recovered documents do not describe a method such as that of the claimed invention or from which it can be deduced, alone or in combination. Therefore, it is considered that the invention of claims 1-5 are new and have inventive activity, as indicated in articles 6 and 8 of Patent Law 11/1986 of March 20. - Claim 6 Document D04 describes a system for measuring harmful electrical disturbances for equipment, comprising: a power module, a measurement preparation module, a communications port, a real-time clock and a microcontroller. Therefore, document D04 affects the novelty of claim 6, according to article 6 of Patent Law 11/1986, of March 20. - Claims 7-10 The structural structural details are mere design options that do not produce any additional technical effect with respect to document D04. Therefore, document D04 affects the inventive activity of claims 7-10, according to article 8 of Patent Law 11/1986 of March 20.
