Key Modules of SKM Software
1. DAPPER: Load Flow and Demand Analysis
The DAPPER module in SKM is designed to handle balanced and unbalanced load flow studies, voltage drop calculations, and load demand evaluations. Engineers use DAPPER to model real-world power systems, assess system behavior under varying conditions, and identify overloaded components. By simulating worst-case scenarios, this module enables professionals to apply preventive actions before system failures occur. DAPPER’s capabilities are essential for planning expansions, optimizing operations, and designing robust electrical systems that remain stable even under abnormal conditions.
2. CAPTOR: Protective Device Coordination
CAPTOR offers comprehensive tools for coordinating protective devices like relays, circuit breakers, and fuses. With time-current characteristic (TCC) curves, engineers can visually represent how each protective device reacts to overcurrents and short circuits. The software ensures that the correct device operates first during a fault, preventing widespread outages or equipment damage. This selectivity is vital for system protection, especially in complex facilities. CAPTOR simplifies what would otherwise be a manual and error-prone process, allowing engineers to automate device coordination with high precision and accuracy.
3. A FAULT: Advanced Short Circuit Analysis
A FAULT is another powerful module within SKM that performs symmetrical and asymmetrical short circuit studies based on industry standards like ANSI, IEC, and IEEE. It identifies fault currents at multiple buses and helps engineers specify equipment ratings accurately. The A_FAULT module can analyze three-phase, line-to-line, line-to-ground, and double line-to-ground faults, providing a complete picture of fault conditions in a system. Proper analysis allows engineers to design systems that can safely handle faults without endangering equipment or personnel, especially in high-power environments where fault energy is massive.
SKM Lifetime License Proof
NFPA 70E and IEEE 1584 Compliance
Arc flash is one of the most dangerous hazards in the electrical industry, and SKM addresses this through its dedicated Arc Flash Evaluation module. This tool calculates incident energy levels, arc flash boundaries, and personal protective equipment (PPE) requirements according to industry standards such as IEEE 1584 and NFPA 70E. Facilities use this analysis to label equipment with proper warnings and train workers for safe operation. The inclusion of this module helps organizations prevent injuries and fatalities, ensures OSHA compliance, and reduces liability from workplace accidents. By accurately determining hazard levels, SKM fosters a safety-first approach in power system design and maintenance.
Industrial Facilities and Data Centers
Industries rely on SKM to ensure electrical continuity, especially in environments where even a brief power interruption can cause significant financial loss. Data centers, for instance, must maintain 24/7 uptime. SKM tools enable load balancing, generator integration, and redundancy planning that guarantees uninterrupted power supply. Additionally, arc flash analysis within these facilities helps in reducing risks associated with high-energy faults in tightly packed equipment rooms.
Utilities and Power Generation
Power utilities use SKM for generation planning, fault simulation, and substation coordination. Accurate modeling of transformers, lines, and switchgear allows utilities to forecast system behavior, optimize network topology, and enhance protection schemes. SKM’s detailed reports support decision-making during upgrades and expansions. Moreover, generation facilities benefit from short circuit and load flow analysis, ensuring synchronization between power sources and stability across the grid. This makes SKM an indispensable part of smart grid modernization strategies.
Oil and Gas Sector
The oil and gas industry, known for its hazardous operating environments, demands reliable and fault-tolerant electrical systems. SKM tools assist in designing explosion-proof networks, assessing arc flash risks, and ensuring correct device coordination. By simulating electrical faults in offshore and onshore platforms, engineers can determine the safest design configurations and prepare contingency plans. SKM also supports international safety standards and helps in audit preparation and risk mitigation, making it the go-to solution for this sector.
Digital Twin and Smart Infrastructure
As industries adopt smart technologies, integration between SKM and Building Information Modeling (BIM) platforms becomes essential. With digital twin environments, SKM models can be imported into Revit or AutoCAD, providing a unified platform for real-time system visualization and lifecycle management. This synergy improves accuracy, accelerates workflows, and facilitates interdisciplinary collaboration between architects, mechanical engineers, and electrical consultants.
SCADA Compatibility and Live Monitoring
SKM’s ability to interface with SCADA systems provides an edge in live monitoring and decision-making. Real-time data from sensors and smart meters can be overlaid on SKM simulations, allowing engineers to monitor system performance and implement predictive maintenance. This integration creates a bridge between planning and operations, ensuring that theoretical models align with actual field conditions. Such synchronization is pivotal for mission-critical infrastructure, where downtime or failure can lead to catastrophic consequences.
Licensing Options for Engineers and Enterprises
SKM offers flexible licensing options for individuals, small engineering firms, and large enterprises. Whether deployed on a standalone PC or across networked workstations, licenses can be tailored to include only the modules required by the user. Subscription and perpetual licensing models are available, with annual support plans that include updates, technical assistance, and access to SKM’s knowledge base. This ensures that users always have the tools and information they need to deliver top-quality work.
