Abstract: Instrumentation equipment used to acquire voltage and current variables, have been an important alternative for the detection of harmonic content in AC networks. This paper presents the design and implementation of the insulation and conditioning cards for sensors that measures voltage and current signals, with emphasis on the design procedure of Antialiasing filters, its importance and its application to harmonic control in a Active Power Filter (APF).

Keywords: Harmonic Detection, Instrumentation Systems, Antialiasing Filters, Acquisition Systems.

Resumen: Los equipos de instrumentación utilizados para la adquisición de variables de tensión y corriente, han sido una alternativa importante para la detección de contenido armónico en redes de alimentación de corriente alterna. Estas variables se utilizan como señales de referencia para sistemas de control de corriente o tensión para convertidores de potencia. Este artículo presenta el diseño e implementación de las tarjetas de aislamiento y acondicionamiento de señales medidas por sensores de corriente y voltaje haciendo énfasis en el procedimiento de diseño de los filtros Antialiasing, su importancia y su aplicación para el control de armónicos en un Filtro Activo de Potencia (FAP).
