Non-instrusive self-powered synchronous voltage-current measurement method based on self-synchronous triggering

To address the significant gap in the availability of comprehensive solutions for passive, wireless, and maintenance-free line voltage monitoring systems, this paper introduces an innovative and advanced technical solution. This novel approach seamlessly integrates the principles of voltage inversion measurement with state-of-the-art non-contact current measurement technology. By doing so, it establishes a groundbreaking self-powered synchronous measurement method that simultaneously captures both line voltage and current data. This integrated approach not only ensures highly efficient and precise data acquisition but also guarantees the accuracy and reliability of the monitoring data. Additionally, it significantly minimizes energy consumption during the crucial stages of signal processing and transmission, thereby substantially enhancing the overall energy efficiency of the system. Moreover, this innovative solution effectively addresses and mitigates numerous inherent drawbacks associated with traditional transformers. These include the complexities involved in insulation design, the high costs associated with manufacturing, and the absence of wireless transmission capabilities. By overcoming these limitations, the proposed solution provides a robust and versatile technical framework that significantly advances the field of line voltage monitoring technology, paving the way for more efficient and reliable electrical systems.
