Item Analysis of Leakage Current Mechanism in Supercapacitor with Experimental Approach(Institute of Electrical and Electronics Engineers Inc., 2022) Bairwa, B.; Pareek, K.; Sarvagya, M.; Yaragatti, U.R.In this paper, we evaluated the leakage current of super capacitor during self-discharge. A three branch electrical equivalent circuit model (ECM) is constructed to estimate voltage response and leakage current of commercially available 2.7 V 350F (BCAP350) double-layer capacitor (DLC). Experimental work carried out with two constant current charging segments 0.25 ampere, and 0.5 amperes. Simulated data shows good agreement with experimental results obtained at electro-chemical workstation CH760e with RMSE and MAE error up to 0.0633, 0.05715, and 0.0759, 0.04173 for 0.25 ampere and 0.5 amperes charging current, respectively. The results confirm that the ECM model is capable to simulate the complex terminal behavior of the super capacitor and provides the means to study its application as an energy storage device. © 2022 IEEE.Item PV Power Prediction and Investigation for Movable Solar PV Module(Institute of Electrical and Electronics Engineers Inc., 2022) Manohar, K.A.; Bairwa, B.; Yaragatti, U.R.; Raghu, C.N.In this paper, A moving solar panel's power output, and solar irradiation output are compared to a fixed solar panel experimentally. The solar module's performance was first measured while it was in a fixed position and then dual axis solar tracker is employed to rotate the solar module to track the sun in two axes while the appropriate measurements were taken. solar modules using solar trackers will increase the output of annual solar irradiation that incident on the module surface compared to a fixed solar module at an optimum tilt angle. A moving solar module produces higher power output than a fixed module. Thus, it produces higher power output which means it utilizes the most of available solar radiation effectively. © 2022 IEEE.Item Development of Fault Detection Method in Cable Using Arduino UNO(Institute of Electrical and Electronics Engineers Inc., 2022) Bairwa, B.; Rathod, S.; Yaragatti, U.R.; Manohar, K.A.This study provides the investigation of underground cable fault. Fault are classified into two type such as symmetrical and unsymmetrical fault. For this fault detection range of about 1m to 2.6 km of the underground cable have been investigated. In underground cable, fault is validating through live tests as per the research knowledge. The underground cable fault are largely caused due to improper insulation, interweave, mesh and other accessories. symmetrical and unsymmetrical fault are present to detect and classify incipient fault in underground cable at the distribution voltage level. The wavelet transformer approach has been used to detect the fault location of the underground fault. This project deal with number of high voltage cable fault location technique with modeling and simulation. © 2022 IEEE.Item Automated Parking Lot Management System Using Number Plate Recognition(Institute of Electrical and Electronics Engineers Inc., 2025) Nagar, R.; Suresha, S.N.; Bairwa, B.In modern era, due to the rapid growth of vehicles had led to a significant increase in parking spaces in areas such as work spaces, business parks etc. Parking management has become a tenacious task to carry out. Wherein, this research paper proposes an Automated parking lot management system using a state-of-the art technology, which is Number Plate Recognition. This Automated parking lot management system using number plate recognition utilizes a Scale Invariant Feature Transform (SIFT) algorithm which aims in providing accurate detection and recognition of the vehicle's number plate. This SIFT algorithm is implemented using MATLAB Simulink. A collection of 136 vehicles dataset is taken to validate and assist system's performance. This system identifies and matches to the vehicle's number plate present in the dataset by using the app camera. When a match is detected, permission is granted for the vehicle to access the parking facility. In the absence of a match, the system impedes the vehicle and prompts the owner to settle the parking fee. The primary aim of this mechanism is to oversee and regulate the ingress and egress of vehicles in the parking area through the utilization of Number Plate Recognition technology. © 2025 IEEE.
