“…This system development model is easy to understand and has simple stages so that the system development procedure will become clearer at each stage. The functional block diagram of the system made in this research design [11] [12] in general can be seen in the following figure: In designing the tool, it is adjusted to the research objective, which is to make a series of current and voltage monitoring in PLTS on an IoT-based On Grid system with the Telegram application [13]. The design of the tool can be seen in Figure 3 as follows: Figure 3 shows that there are two color lines: (1) the black line is the process of electricity flow from the source to the load, and (2) the green line is a process for monitoring current and voltage from sensor data retrieval to Telegram.…”

Utilization of solar energy through solar power plants is the right solution to reducing dependence on conventional energy consumption. The amount of electrical energy used can be controlled by mobile devices using the Internet of Things (IoT). The utilization of the Telegram application for monitoring the current and voltage of solar energy-based electrical energy is a new method. This study aims to develop an IoT-based PLTS current and voltage monitoring tool for the PLN On Grid system with the Telegram application. The source of voltage in this study comes from PLN and solar panels. The research method uses an experimental approach by collecting current and voltage data through direct test monitoring using a multimeter and the Telegram application. Telegram Bot is a social media application used to send commands to electrical loads and receive feedback in the form of current (A) and voltage (V) parameters. The test was carried out with a model without a load and with a load. The results of monitoring the current and voltage produced by PLTS based on Telegram data and measurements using a multimeter are not much different. The average percentage value of error between DC source measuring instruments is 0.02%, and that between AC sources is 0.114%. The development of IoT-based current and voltage monitoring is very effective because it can facilitate the monitoring of PV mini-grids.

“…In passive force-based sensors (see figure 2(a)), the charges are generated by electric induction of the field to be measured. Since the force is proportional to the electric field strength and the charge, the force on the structure is proportional to the square of the electric field strength (F ∝ E 2 ) [16][17][18]. Therefore, passive systems are non-linear and the polarity of the field cannot be inferred with such a sensor.…”

Due to the necessary transition to renewable energy, the transport of electricity over long distances will become increasingly important, since the sites of sustainable electricity generation, such as wind or solar power parks, and the place of consumption can be very far apart. Currently, electricity is mainly transported via overhead AC lines. However, studies have shown that for long distances, transport via DC offers decisive advantages. To make optimal use of the existing route infrastructure, simultaneous AC and DC, or hybrid transmission, should be employed. The resulting electric field strengths must not exceed legally prescribed thresholds to avoid potentially harmful effects on humans and the environment. However, accurate quantification of the resulting electric fields is a major challenge in this context, as they can be easily distorted (e.g., by the measurement equipment itself). Nonetheless knowledge of the undisturbed field strengths from DC up to several multiples of the fundamental frequency of the power-grid (up to 1\,kHz) is required to ensure compliance with the thresholds. Both AC and DC electric fields can result in the generation of corona ions in the vicinity of the line. In the case of pure AC fields, the corona ions generated typically recombine in the immediate vicinity of the line and, therefore, have no influence on the field measurement further away. Unfortunately, this assumption does not hold for DC fields and hybrid fields, where corona ions can be transported far away from the line (e.g., by wind), and potentially interact with the measurement equipment yielding incorrect measurement results. This review will provide a comprehensive overview of the current state-of-the-art technologies and methods which have been developed to address the problems of measuring the electric field near hybrid power lines.

“…Providing this information relies heavily on sensors [47,48]. However, conventional sensors have limitations in capturing detailed power quality data or detecting transient events that can affect grid stability and power delivery [48,49]. For example, conventional voltage sensors, such as electromechanical or electronic voltage transformers, may be limited in accurately capturing small voltage fluctuations or harmonic distortions [48,50].…”

The vital role of civil engineering is to enable the development of modern cities and establish foundations for smart and sustainable urban environments of the future. Advanced sensing technologies are among the instrumental methods used to enhance the performance of civil engineering infrastructures and address the multifaceted challenges of future cities. Through this study, we discussed the shortcomings of traditional sensors in four primary civil engineering domains: construction, energy, water, and transportation. Then, we investigated and summarized the potential of quantum sensors to contribute to and revolutionize the management of civil engineering infrastructures. For the water sector, advancements are expected in monitoring water quality and pressure in water and sewage infrastructures. In the energy sector, quantum sensors may facilitate renewables integration and improve grid stability and buildings’ energy efficiency. The most promising progress in the construction field is the ability to identify subsurface density and underground structures. In transportation, these sensors create many fresh avenues for real-time traffic management and smart mobility solutions. As one of the first-in-the-field studies offering the adoption of quantum sensors across four primary domains of civil engineering, this research establishes the basis for the discourse about the scope and timeline for deploying quantum sensors to real-world applications towards the quantum transformation of civil engineering.
