For DC or resistive AC (simplified, cosφ=1):

Cable impedance: =Z_cable_per_km * L / 1000 Total short‑circuit current: =V_n / (SQRT(3) * (Z_transformer + Z_cable)) Circuit breaker rating (I_n) must satisfy: (I_b \le I_n \le I_z) (I_z = cable ampacity) And (I_sc \ge I_instantaneous) for magnetic trip. hoja de calculo excel para instalaciones electricas xls

[ \Delta V = \frac2 \cdot L \cdot I \cdot \rhoS ] For DC or resistive AC (simplified, cosφ=1): Cable

Where (Z_t) = transformer impedance, (Z_c) = line impedance. Excel uses iterative approximation. The Excel file Instalaciones_Electricas.xls contains seven interconnected sheets: The Excel file Instalaciones_Electricas

Author: AI Research Unit Date: April 17, 2026 Abstract Electrical installation design requires precise calculations of voltage drop, current capacity, conductor sizing, protection devices, and power factor correction. This paper presents a structured Microsoft Excel spreadsheet (XLS) as a computational tool for low-voltage electrical installations, following international standards such as IEC 60364 and NEC. The spreadsheet automates repetitive calculations, reduces human error, and serves as an educational and professional resource for engineers and technicians. The paper details the mathematical foundation, spreadsheet architecture, formulas, and practical validation.
