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.
Where (Z_t) = transformer impedance, (Z_c) = line impedance. Excel uses iterative approximation. The Excel file Instalaciones_Electricas.xls contains seven interconnected sheets: hoja de calculo excel para instalaciones electricas xls
Excel spreadsheet, electrical installation, voltage drop, conductor sizing, short-circuit calculation, XLS tool. 1. Introduction Electrical installations in residential, commercial, and industrial buildings must comply with safety, efficiency, and regulatory standards. Manual calculations are time‑consuming and error‑prone. Spreadsheet software like Microsoft Excel offers a flexible, transparent, and accessible platform to automate these calculations.
