SKM PowerTools, developed by SKM Systems Analysis, Inc., is a comprehensive software suite for modeling, analyzing, and documenting electrical power systems in industrial, commercial, and utility facilities. Often referred to as PTW (Power*Tools), it helps engineers design safer, more reliable networks, validate equipment ratings, and demonstrate compliance with applicable standards.
Key capabilities include:
- One-line modeling: Build intelligent single-line diagrams that serve as a live model for studies and documentation.
- Short-circuit and load flow analysis: Evaluate fault duties, voltage drop, transformer and feeder loading, and equipment ratings.
- Protection and coordination: Create and compare time-current curves, select device settings, and assess selectivity using extensive manufacturer device libraries.
- Arc flash hazard analysis: Calculate incident energy and boundaries in accordance with widely used methods (such as IEEE 1584) and generate clear, standards-aligned labels and reports to support NFPA 70E programs.
- Motor starting and transients: Assess voltage dips and starting strategies to ensure process reliability and equipment performance.
- Harmonic analysis: Identify sources of distortion, evaluate resonance risks, and support filter design to manage THD.
- Equipment sizing and verification: Check cables, transformers, and protective devices against thermal, interrupting, and coordination requirements.
- Scenario and what-if studies: Compare design options, contingencies, and operating states within a single project.
- Reporting and documentation: Produce detailed, customizable reports and drawings that streamline reviews, audits, and maintenance planning.
Designed for Windows and structured with modular licensing, SKM PowerTools scales from single-user projects to enterprise deployments. It is widely used by consulting engineers, EPCs, utilities, and facility owners to improve safety, reduce risk, and optimize electrical system performance throughout the asset lifecycle.
SKM PowerTools is developed by SKM Systems Analysis, Inc.. The most popular versions of this product among our users are: 6.0, 6.5 and 7.0. The name of the program executable file is PTW32.exe.
