SKM Power*Tools
What SKM Power*Tools is
SKM Power*Tools is paid electrical engineering software for analyzing power-system behavior and designing distribution systems. Its integrated studies cover coordination, arc-flash and equipment evaluation, cable ampacity, ANSI and IEC fault calculations, motor starting, harmonics, transient simulation, unbalanced systems, reliability, DC analysis, wiring, grounding, cable pulling and data exchange. The Arc Flash Evaluation module calculates incident energy and arc-flash boundaries by location. DAPPER adds a one-line interface, component library, fault analysis, load flow, demand-load studies, cable and transformer sizing, and panel schedules. A_Fault performs calculations under ANSI C37 standards. Data Exchange handles tab-delimited, CSV and SKM XML files and interfaces with Autodesk Revit and Intergraph SmartPlant Electrical. PTW runs on Windows; SKM Mobile supports iOS and Android field collection, result review and project sharing. Mobile-desktop transfers require MySKM Cloud.
