Electrical Planning for Environmental Engineering Building Faculty of Industrial Engineering Andalas University

Abstract

Abstract— Technological advancement has made electrical energy crucial in daily life and development. Electrical installations in high-rise buildings play a vital role in human safety and fire prevention due to short circuits. This study designs the electrical system for the Environmental Engineering Building at the Faculty of Engineering, Andalas University, covering the single-line diagram, electrical power calculations, lighting needs, power outlets, and other components. The research methods include data collection, needs analysis, electrical system design, component calculation, and cost estimation.

The results indicate the need for 200 lighting points, 90 single-phase power outlets, and 2 three-phase outlets. The total power for the lighting panel is 47.82 kW, and for the AC panel, it is 278.8 kW. The total current for the lighting panel is 256 A, and for the AC panel, it is 508.7 A. The design uses NYM and NYY cables as well as 4 MCCBs. A 250 kVA transformer and generator are used, along with 6 grounding points and a lightning arrester.
