| Partial discharge in the power systems equipment can cause the destruction of the insulation system and the occurrence of accidents. There are various methods to identify and measure partial discharge, one of which can be mentioned as the acoustic method. Commercial sensors in the market usually have a high price. For this issue, a low-cost piezoelectric sensor and a built-in low-noise preamplifier and filter for partial discharge measurements have been designed. In this article, the effect of the sensitivity and frequency response of the acoustic sensor on time and frequency domain measurements has been discussed. The performance of the proposed AE sensor has been investigated through simulation and experimental studies. The obtained results indicate that the proposed low-cost AE sensor has a good performance and is capable of PD monitoring within power transformers. | ||
