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 Durability performance of one-part alkali-activated self-compacting concrete mixes under aggressive and elevated temperature conditions(Elsevier B.V., 2025) Mahendra, K.; Narasimhan, M.C.; Rathod, S.; Das, A.K.; Prakash, G.B.The growing demand for sustainable, high-performance materials in modern construction has driven the development of advanced concrete technologies. This study introduces one-part alkali-activated self-compacting concrete (OPASC) as a practical, safe, and user-friendly alternative to conventional Portland cement-based concretes. Selected mixes with compressive strengths exceeding 70 MPa were evaluated for durability under aggressive conditions, including extended exposure to 5 % sulfuric acid and 5 % magnesium sulfate up to 180 days. The thermal stability of these candidate mixes was also assessed by subjecting the mixes to sustained temperatures ranging from 200 °C to 800 °C. Chloride-ion resistance of these mixes was examined under bulk diffusion tests. Key durability indicators, including water absorption, permeable voids, and sorptivity, were quantified to evaluate matrix impermeability. The results revealed compressive strength losses of 25–32 % under acid exposure, 7–15 % under sulfate exposure, and 30–42 % under thermal exposure, with chloride diffusion coefficients ranging from 0.21 × 10?12 to 0.32 × 10?12 m2/s, indicating high resistance to ionic ingress. The mixes also exhibited low water absorption (3–4.5 %), lower soptivities (0.0024–0.0013 mm/s1/2), and much reduced permeable voids (4.3–5.5 %), reflecting an impermeable, dense matrix. Microstructural analyses using SEM-EDS and XRD revealed that degradation under acid and sulfate conditions is primarily attributable to the decalcification of C/N-A-S-H gels, accompanied by the recrystallization of stable aluminosilicate phases. Finally, the environmental sustainability evaluation, which considered both embodied energy and carbon footprint, verified the superior environmental friendliness of OPASC mixes relative to conventional concrete. These findings confirm that OPASC exhibits superior chemical and thermal durability, reduced permeability, and enhanced resilience, thereby establishing it as a sustainable and practical solution for modern infrastructure applications. © 2025 Elsevier B.V.
