Abstract

Calle Ramiro de Maeztu, 7 E-28040 Madrid Se describe un procedimiento concebido para detectar eventos asociados a descargas parciales (DPs) en equipos e instalaciones de alta tensión capaz de diagnosticar el estado del aislamiento en tiempo real, gracias a la discriminación del ruido de las señales de DPs mediante el uso en paralelo de multiprocesadores, los cuales además se utilizan para la discriminación, también en tiempo real, de diferentes fuentes productoras de DPs situadas en un mismo emplazamiento o en diferente. Para la identificación de las diferentes fuentes productoras de DPs se forman grupos tridimensionales mediante las coordenadas de tres parámetros característicos de cada pulso: parámetro relacionado con el tiempo de frente del impulso, parámetro relacionado con el tiempo de cola y parámetro relacionado con la frecuencia del pulso. El procedimiento de diagnóstico permite que sea aplicado utilizando como fuente de tensión la propia tensión de red o mediante generadores independientes, en particular se describe una novedosa fuente de tensión concebida al efecto. También se describe un sistema de puesta en práctica del procedimiento que comprende los medios de captura de las DPs, medida y análisis necesarios.
