Proposta de desenvolvimento de um IED para medições de descargas parciais a baixo custo

Abstract

In this work, a proof of concept of a data acquisition system for partial discharges was proposed. It is a system composed of hardware and software elements that make up an IED, including an acquisition module, a data processing unit and a human-machine interface. These characteristics, combined with several connectivity and mobility features, aim to create a device for use in the field. The system was submitted to tests with the objective of evaluating its data acquisition capacity and determining the minimum feasibility of the system, as well as its limitations, mainly. The preliminary results indicated a system capable of recording some pulses, but with a number of limitations regarding recording. As for the usability of the IED project, the system was considered relevant and promising, since it brings together in a single physical set sophisticated processing elements, advanced communication interfaces and all the basic accessories that give the system autonomy for use in field activities. All these elements contribute to creating a technological support structure for field work related to electrical measurements.
