Description

FIELD OF THE INVENTION [001] The present invention relates to a device for measuring electrical parameters of an electrical installation. In particular, the device of the present invention is capable of storing electrical data, performing electrical data telemetry and reporting it to a control center. BACKGROUND OF THE INVENTION [002] Electrical parameter measuring devices are devices used by electricity distribution companies to record consumers' electricity consumption, and can differentiate usage according to time slots and applicable tariffs. Through sensors and algorithms, these devices not only count the amount of electricity consumed, but also record the exact times of use, allowing the application of differentiated tariffs for peak periods (i.e., high electricity consumption) and off-peak periods. This encourages consumers to adjust their consumption habits, resulting in better load distribution and greater energy efficiency. [003] The use cases for electrical parameter measurement devices are varied and include both residential and commercial and industrial environments. In homes, these devices help reduce costs related to electricity consumption by encouraging the use of appliances during off-peak hours. In commercial environments, such as offices and shops, they allow for more efficient management of electrical appliances, such as lighting and air conditioning systems, aligning consumption with off-peak hours. In the industrial sector, where electricity consumption is significantly higher, the devices enable the optimization of production processes and the reduction of peak demand, contributing to the sustainability and competitiveness of operations. In short, electrical parameter measurement devices are essential tools for the intelligent and economical management of electricity, benefiting both distributors and end consumers. [004] However, a disadvantage of state-of-the-art electrical parameter measurement devices relates to their installation and configuration, which can be complex, requiring advanced technical knowledge and hindering adoption by residential users and small businesses. Research by the Harvard Business Review indicates that 70% of these technology projects fail due to implementation complexity. [005] Furthermore, existing electrical parameter measuring devices do not assess power quality parameters such as harmonics and power factor, which can negatively affect the operation of electrical appliances. Studies show that harmonic distortions can reduce the lifespan of equipment by up to 30%. [006] Another deficiency of the state of the art relates to the fact that most existing electrical parameter measuring devices have limited communication capabilities, generally restricted to local connections such as Wi-Fi, making remote monitoring and integration with intelligent management systems difficult. [007] Furthermore, state-of-the-art electrical parameter measurement devices do not have independent storage memory, limiting the ability to record and analyze detailed historical data, which may be lost in case of Wi-Fi connection instability. [008] State-of-the-art electrical parameter measuring devices are also designed to operate on specific electrical networks, for example, on single-phase, two-phase or three-phase electrical networks, which limits the applicability and adaptability of these devices to different electrical network configurations. [009] Furthermore, state-of-the-art electrical parameter measuring devices are not suitable for weathering, reducing their service life when installed in locations exposed to adverse weather conditions. [0010] Therefore, the need for an electrical parameter measurement device with simplified installation and configuration for a wider audience is evident, with power quality measurement functionalities, multiple communication and data transmission options, and internal storage that allows the recording of historical data to avoid data loss and enable later analysis. DESCRIPTION OF THE INVENTION [0011] The overall objective of the present invention is to provide an intelligent electrical parameter measuring device capable of accurately measuring the electrical parameters of an electrical installation, transmitting data through different communication media to a control center, storing the acquired data locally, and providing greater flexibility and simplification in its installation and configuration. [0012] A particular objective of the present invention is to reduce the complexity of installing and configuring the electrical parameter measuring device by providing the device with a color graphic display, buttons and LEDs, the device also being operable by a mobile application, making it accessible to a wider audience and facilitating the commissioning and maintenance of the device. [0013] Another particular objective of the present invention is to provide the device with means for measuring multiple electrical parameters of an electrical n
