The voltage sensor was tested on the experimental platform of simulating three-phase transmission line. The insulation structure design of the sensor is simple and its volume is small phase difference of sensor measurement is effectively reduced through optimization design of the electrode and voltage division ratio and measurement accuracy are increased. By aiming at the current problems of electric transformation, based on electrostatic induction principle, this paper designed a non-contact voltage sensor and gained detection signal of the sensor through electrostatic coupling for the electric field generated by electric charges of the conductor to be measured. As a result, the detection accuracy of transformer is reduced, a huge phase difference exists between detection signal and voltage signal to be measured, and the detection signal cannot accurately and timely reflect the change of conductor voltage signal to be measured. Transformers are often large in volume and heavyweight, their insulation design is difficult, and an iron core or multi-grade capacitance voltage division structure is generally adopted. Presently, more and more electric power systems are adopting potential transformer and capacitance voltage transformers. This enables the system to respond faster when compared to using other microcontrollers.Ī voltage transformer, as voltage signal detection equipment, plays an important role in a power system. The robot uses an ATMega2560 as its microcontroller since it provides higher transmission rate and higher clock speed with more memory in terms of RAM and Flash. The main feature of the system is when it detects obstacles it avoids the obstacle after avoiding the obstacle it again finds the black line path and returns to the original path. The system can be used in cost efficient manner and can handle multiple operations. The system uses several sensors that are mounted on it as well as in the home so that it can detect any breach in security or any abnormal situation in the household and inform the owners immediately as well as raise an alarm so that those nearby can take effective actions. This study deals with creating a solution for such a situation in the form of a small robot that can take care of the security in the home. The primary concern of every household when they leave their home is safety of the home as well as its protection. Many consider it to be the largest example of an IoT. The grid is exploding into a network of things. It is being supplemented and may ultimately be supplanted by many smaller networks with literally millions of distributed generation, storage, and energy management nodes. For a variety of reasons, this legacy grid approach is proving to be nonviable for the present and the future. electric utility grid has, until now, been a patchwork of monolithic, weakly interconnected, synchronous ac grids powered by a few thousand very large power plants that are centrally monitored and controlled. Cisco has predicted that 50 billion new connections will be made in this IoT by 2020. This exponential growth has primarily been as an Internet of Things (IoT). Although it began as an Internet that connected people, by 2008 it connected more things than people. The Internet has resulted from revolutionary advances in electronics, telecommunications and information technologies, devices, and applications. Over the next 63 years, we will meet world needs for cheap and clean energy by building the Enernet. In this view, the proposed smart power meter intends to support the smart power grid to monitor electricity among different nodes in an efficient and effective way.īob Metcalfe, inventor of the Ethernet and a well-known technology visionary, once said, Over the past 63 years, we met world needs for cheap and clean information by building the Internet. So, even energy coming from a far node should be preferred if it has higher quality standards. Energy cannot be now routed by considering just only the criterion based on the simple shortening of transmission path. Now energy flow must be able to change its direction according to needs. The new scenario has changed the way to exchange energy in the grid. Information concerning the power consumption and power quality could allow the power grid to route efficiently the energy by means of more suitable decision criteria. The described power meter uses the metrics proposed in the IEEE Standard 1459-2010 to analyse and process voltage and current signals. The authors provide an outline of the potentialities of the sensing systems and IoT to monitor efficiently the energy flow among nodes of electric network. In detail the project, development and experimental validation of a smart power meter are described in the following. This paper aims to describe the role of advanced sensing systems in the electric grid of the future.
