During January 2025, Manny Gim focused on improving data accuracy within the SCFormulaElectric/USC-Electrical-Systems repository, specifically addressing the Electrical Systems Formula (ESF) calculations used in bus bar design. Manny identified and corrected data inconsistencies in the ESF Bus Bar Excel files, ensuring more reliable electrical design calculations without altering production code. This data-only correction approach minimized regression risk and maintained system stability while enhancing traceability for future audits and design reviews. Manny’s work leveraged Excel and data validation skills, contributing to improved downstream design reliability and reducing the likelihood of errors in electrical system engineering processes.
