Abstract: The cost of electronic equipment falls down but the nuclear instruments remain costly. Under this consideration a Low-Power Variable High Voltage Power Supply has been designed using state-of-the-art-technology. The design is essentially focused upon low power electric appliances such as GM detector, Scintillation detector, Camera flash light etc. In this design 6-volt DC battery is used as its input power supply. The designed power supply provides AC output voltage ranges from 450 volt to 2000 volt. It included the facilities for adjusting at any fixed value within the above-mentioned ranges. The power rating of the device is 1 W. The proposed system has been tested and found to be reliable and satisfactory results. The load regulation is 1.03% and maximum load tested for this device.....

Abstract: Background: The agriculture sector is extremely crucial for economic growth in every country. Thus, there is a need for disease detection in crops, which is vital in the agricultural area, as a disease in vegetation is a naturally occurring phenomenon. If adequate attention is not taken in this region, it can have critical costs for plants, thus impacting the quality of the output, volume, and productivity. For example, a disease known as "tiny leaf disease" is a dangerous illness that affects pine trees. Materials and Methods: A plant diagnostic system using an automated technique is beneficial since it decreases the time of supervision required in large crop fields and identifies illness at an early stage. Results: This research paper provides an image processing technique that, when combined with algorithms, can be utilised to forecast disease accurately.......

Abstract: The SCADA system was developed to provide fault isolation operation, monitoring and controlling functions for various industrial applicationswhich includes data collection and storage for future analysis.This paper encompassesstudyof the development of a Supervisory Control and Data Acquisition (SCADA) based on Remote Terminal Unit (RTU). An embedded Ethernet controller is used as RTU to act as converter for Human Machine Interface (HMI) and to interact with analog and digital input and output modules. RTU is the master and digital input and output modules are the slaves. RTU will initiate the transaction with the digital input and output modules and feed the data's to Communication Feed Server. The integration of the SCADA system and the substation automation system results in a real‐time wide‐area monitoring and control of substation by controlling not only in civil but also in Military Station.

Abstract: Due to higher generated power and better wind conditions, wind turbines are getting taller and the blade length are increased bringing them closer to lightning. Modern wind turbines are predominantly protected by the single tip receptor method due to weight related matters. However, strikes attaching inboard of the blade are highly reported. Indicating that the single tip receptor might not give adequate protection to inboard of longer blades. It will be very risky to assume that a single receptor at the blade tip can protect an infinite blade length. It is therefore necessary to investigate the distance from the blade tip at which the single tip receptor is no longer effective. This paper investigates how long a blade becomes before the effect of the tip receptor is no longer felt.........

Abstract: Touch voltage is one of the voltage differences that occur during the flow of ground fault current. At a small voltage value the resulting effect is not very significant but at a certain voltage value the effect is very dangerous and can even lead to human death. The Earth Leakage Circuit Breaker (ELCB) time trip is not affected by the resistance of the human body. With the application of the ELCB in an electrical installation system, it is hoped that the danger caused by the touch voltage can be minimized so that the system is safe for humans. To further refine the ELCB system, in this study, adding additional devices to the ELCB circuit; namely the ESP8266 microcontroller......
