Diseño y construcción de una resistencia de frente y una de cola para el generador de impulsos de tensión tipo maniobra del Laboratorio de Alta Tensión de la Universidad Distrital Francisco José de Caldas

Abstract

High-voltage laboratories can be classified according to their equipment and scope, distinguishing between accredited and teaching laboratories. Within the latter category is the High Voltage Laboratory of Universidad Distrital Francisco José de Caldas (LAT-UD), where academic, research, and extension activities are carried out. In response to the impossibility of generating switching impulses due to the lack of required components, this work addresses the design, construction, and validation of a front resistor (58 kΩ) and a tail resistor (118 kΩ) for the switching impulse generation circuit of the LAT-UD. Based on theoretical values validated in ATP/EMTP, a modular construction approach was adopted, adjusting the electrical design to the availability of commercial high-voltage components, and defining the internal arrangement, encapsulation, and labeling using Fusion 360®. Frequency sweep, electrical stress, and impulse generation tests confirmed linear behavior up to 80 kHz, the suitability of air as the insulating medium, and compliance with standardized front and tail times. As a result, the LAT-UD now has new components that expand its technical capabilities, supporting academic training and research in high voltage and electromagnetic compatibility.
