Rede de sensores sem fio aplicada ao monitoramento de transformadores.

Abstract

This work describes the development of a system capable of remotely monitor some parameters related to energy quality in distribution transformers. A device intended to measure signals of voltage, current and temperature, sending these data to a personal computer via a ZigBee wireless based protocol was developed. In addition, a C# based program developed was develped, in which the user, using a personal computer, is able to visualize the voltage and current waveforms. The RMS voltage and current, power, power factor and temperature values are also available for visualization. Finally, these values were logged for later analysis.
