Abstract

La presente se refiere a un puente de medida modular (100) para determinar un error de medida e de un transformador de medida (10) conectado a una fase (30) de una línea de alta tensión, que comprende: un primer elemento (110) para medir en un instante de tiempo determinado un primer valor de tensión Vʳₑᶠ de un transformador de medida de referencia (20) conectado a la misma fase (30); un segundo elemento (120) para medir en dicho mismo instante de tiempo un segundo valor de tensión Vₘₑᵈ de dicho transformador de medida (10); y, un comparador (130). Dichos primer y segundo elementos (110, 120) además comprenden medios de transmisión (140) para transmitir dichos primer y segundo valores de tensión Vʳₑᶠ y Vₘₑᵈ al comparador (130); y dicho comparador (130) comprende medios de recepción (150) para recibirlos. En respuesta a recibir el comparador (130) dichos primer y segundo valores de tensión Vʳₑᶠ y Vₘₑᵈ, el comparador (130) está configurado para calcular el error de medida epsilon del transformador de medida (10).This refers to a modular measuring bridge (100) for determining a measurement error e of a measuring transformer (10) connected to a phase (30) of a high voltage line, comprising: a first element (110 ) to measure a first voltage value Vʳₑᶠ of a reference measurement transformer (20) connected to the same phase (30) in a given time; a second element (120) for measuring at said same instant of time a second voltage value V (of said measuring transformer (10); and, a comparator (130). Said first and second elements (110, 120) further comprise transmission means (140) for transmitting said first and second voltage values Vʳₑᶠ and Vₘₑᵈ to the comparator (130); and said comparator (130) comprises receiving means (150) for receiving them. In response to receiving the comparator (130) said first and second voltage values Vʳₑᶠ and Vₘₑᵈ, the comparator (130) is configured to calculate the epsilon measurement error of the measurement transformer (10).
