Database Building with Microsoft Excel for Voltage Drop Calculation according to Thai Electrical Code 2013 with C++ Builder

Abstract

Electrical system design according to installation standard complies with an electrical code which concerns about numeric values of tabular data to use in the design calculations. This paper presents the development of computational methods for voltage drop calculation of circuit conductors in the electrical system design by using the tables of voltage drop of Thai Electrical Code 2013. The tables of voltage drop will be modeled by abstract tables that express as labeled sets. Their labeled domains can be used to crate database system in the file format of Microsoft Excel for the data processing through component object model (COM) technology of Microsoft. This data processing of voltage drop calculation is implemented by C++ programing language of C++ Builder software then the object-oriented programming (OOP) and visual component library (VCL) can be used to develop graphical user interface (GUI) application on Windows operating system.
