Generally, the ease of implementation combined with the costs involved are prioritized, which leads to the installation of a single sensor. However, this can decrease the reliability of the results and make the system dependent on the good functioning and durability of the sensor, generating frequent maintenance and recalibration costs. In this sense, a solution consists of using multiple redundant sensors enabling the use of fault detection and data fusion techniques for a more accurate estimation. In this article, a low-cost non-invasive ultrasonic level measurement system using data fusion techniques and online supervisory monitoring is presented. In this way, the process of construction and integration of hardware and software is described, as well as its experimental results.","PeriodicalId":348937,"journal":{"name":"2022 6th International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117211772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several non-destructive methodologies have been developed to enhance the reliability of power transmission and distribution. In this context, insulators play a key role in electrical systems since they allow the connection of the power grid to electrical machines, cables, transformers, etc. Among several flaws, the most common incipient failures in the insulators are characterized by poor contacts and partial discharges. These unconformities can lead the insulator to total failure and impair the power transmission. Once each type of failure requires different maintenance actions, this article presents a new approach to perform the differentiation between poor contact fault and partial discharge activity using thermal analysis. Besides the classification, this work evaluated the evolution of the faults. Several tests were carried out, and the two types of flaws were applied to an insulator. Thermal images were captured, and the new TSTD (Temperature Standard Deviation) index was used to achieve the classification.","PeriodicalId":348937,"journal":{"name":"2022 6th International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133490905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are different approaches for extracting the resonance frequency, and one of the most efficient and explored methodologies is the phase-locked loop (PLL) system. One possibility to implement this system is with off-the-shelf analog devices and data-acquisition platforms. This alternative is relatively easy to implement, but there are some inconveniences, such as the need for several connections with coaxial cables between the devices, the considerable occupied space to implement the circuit, the use of adapters, increased propensity to external noise, both electrical and mechanical, besides the difficulty of making changes in the circuit topology. In this work, the use of a software-defined radio (SDR) platform with the LabVIEW environment is demonstrated as an alternative of a faster and reliable PLL implementation with only one component. A resonant cavity sensor is used to validate the implemented system. The preliminary results show that the system was able to properly track the resonance frequency of the sensor and that it can be a very useful platform to test different control strategies.","PeriodicalId":348937,"journal":{"name":"2022 6th International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125062298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MOS diodes operating with stationary width of the depletion region at a constant reverse current are proposed for X-ray detection using an Al/SiO2(2.20 nm)/Si-P structure fabricated on 10 Ω.cm substrates. A miniature X-ray system (Mini X model from Amptek) was used to illuminate the diodes, at 2 cm away, inside of an aluminum chamber to protect against the X-ray radiation. As a result, the MOS diodes showed good voltage response as function of the bias voltage of the X-ray tube for flux varying from 0 to around 500 mSv/h. In this case, the MOS voltage response increased from 0 to 0.25 mV for the X-ray bias voltage varying from 0 to 40 kV at a filament current of 50 µA. X-ray detection in a constant reverse voltage mode for the MOS diode was unfeasible due to poor current response superimposed to the background electrical noise. On the other hand, unlike the MOS diode, the PIN diode showed good current response in the constant reverse voltage mode as function of the bias voltage of the X-ray tube for flux varying from 0 to around 500 mSv/h. It was noteworthy that the PIN current response increased proportionally with the bias voltage from and 0 to 40 nA at a reverse biasing of -5 V, which are similar to the results reported in the literature for PIN diodes.","PeriodicalId":348937,"journal":{"name":"2022 6th International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127269532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, there are numerous ways to perform its estimation, however, the usual mechanical anemometers are rudimentary and present a considerable margin of error due to the friction between parts and the inertia of the system. Therefore, there is a greater tendency for the use of ultrasonic anemometers, which are based on the calculation of the time of flight of the ultrasonic wave, that is, the time interval required for a wave emitted from a transmitter ultrasonic transducer to reach a receiving transducer. Among the ways of estimating the time of flight of the ultrasonic wave, there are methods based on time intervals and others on digital signal processing, but there are, on the other hand, those based on artificial intelligence. In this article, an artificial intelligence model based on Artificial Neural Networks capable of estimating the time of flight of the ultrasonic wave is presented.
