University, when a coke machine was connected to the internet and was able to report its performance, and whether a newly loaded coke drinks were cold [1]. However, the term “IoT” was birthed in 1999 at MIT with the initial intention of promoting the RFID technology [2].The internet on its own, has tremendously grown from a network that comprises few nodes to a global network which services billions of users. The cost reduction and miniaturization of electronic devices have further provided a big opportunity to further increase the use of the internet into a whole new realm – the realm of smart objects. Smart objects simply connote everyday physical objects e.g. cars, wearable, traffic lights etc. that have been enhanced by computational elements to improve local intelligence and cyberspace connectivity. These computational elements, which can be electronic devices, sensors, software, network connectivity and control systems, reconcile the physical world with the information world when attached to physical devices. They process data from the sensor and enable wireless communication link to the internet thereby making a smart object a cyber- physical system [3]. The IoT is simply the internetworking of smart objects that enables the collection and sharing of data; hence, improving value, processes and service. ![](https://maker.wiznet.io/uploads/2022/07/Screenshot-2022-07-20-115625-300x168.png)![](https://maker.wiznet.io/uploads/2022/07/Screenshot-2022-07-20-115640-300x205.png) Methodology A typical protection system to be controlled and monitored is modeled using a “relay controlled” circuit and a “switch”circuit. The “relay circuit” represents a typical protective relay while the “switch” circuit represents a trip circuit breaker. To control the protection system, a MIFI, an Ethernet Shield, and an Arduino UNO are used. A web page is the user’s interface with the whole system and it communicates with the microcontroller on an Arduino UNO board through a web server that can be accessed over the internet using the MIFI and the Ethernet Shield. The communication among all the components in this system, over the internet, exemplifies the concept of the IoT. ![](https://maker.wiznet.io/uploads/2022/07/Screenshot-2022-07-20-115710-300x199.png)![](https://maker.wiznet.io/uploads/2022/07/Screenshot-2022-07-20-115723-300x198.png) 2. SYSTEM SCHEMATICS AND COMPONENTS DIAGRAMS Two different circuits were used in this work for forward control of the protection system, and for feedback monitoring system. Modeling The protection system used in this project is a prototype of a practical protection system in industries and power systems. This prototype is used because of the difficulty in simulating an overload. CONCLUSIONS This paper has been able to meet most of its objectives. A reliable and real time control system has been designed and implemented so that protection systems can be controlled from anywhere over the internet, so no contact needs to be made with the device or system in use. Also, a reliable feedback monitoring system has been designed and implemented such that from the website, the state of the relay can be known. A graph that can be displayed on the website has been designed so that the number of failure occurrences or trips can be known over a period of time. 5. RECOMMENDATIONS The work described in this paper was designed with practicality in mind so that it can be applied in industries and power systems. Therefore, further improvements can still be made in the work reported here to make it more useful in the industry and more adaptable to other device. --- Source: https://maker.wiznet.io/mayuri/projects/iot-for-power-system-protective-devices/
