JNTUH B.Tech 4th year (4-1) Electrical Estimating and Costing gives you detail information of Electrical Estimating and Costing (Elective-II) R13 syllabus It will be help full to understand you complete curriculum of the year.
Objective
Emphasize the estimating and costing aspects of all electrical equipment, installation and designs to analyze the cost viability. Exposure to design and estimation of wiring, design of overhead and underground distribution lines, substations and illuminations design. These techniques should help the students to successfully estimate costing of the products / projects that are part of our every day usage.
