What SKM Power*Tools is
SKM Power*Tools is paid electrical engineering software for analyzing power-system behavior and distribution equipment on Windows, with related mobile apps for iOS and Android. Its study modules cover fault calculations under ANSI and IEC methods, load flow, coordination, arc-flash evaluation, equipment evaluation, cable ampacity, motor starting, harmonics, transient simulation, unbalanced systems, reliability, DC analysis, wiring and data exchange. The Arc Flash Evaluation module calculates incident energy and arc-flash boundaries for each location. DAPPER provides a one-line interface with a library, fault analysis, load flow, demand load, cable and transformer sizing, and panel schedules. Data Exchange handles tab-delimited, CSV and SKM XML files and interfaces with Autodesk Revit and Intergraph SmartPlant Electrical. SKM Mobile supports field-data collection, result review and project sharing. MySKM Cloud transfers projects between mobile and PTW desktop, with permission controls, but requires a subscription for full exchange.
