Need Guidance on Aspen One Liner Breaker Capacity Study

[Singh1234]

I have a project at my workplace for Breaker Capacity Study using Aspen One Liner. Is anyone familiar with this type of study ? you guide me step-by-step on doing this study. Thanks

Yes, a Breaker Capacity Study using Aspen OneLiner involves several steps. First, set up the software and input the system model, including buses, transformers, lines, loads, and breakers. Next, define electrical parameters for each component. Enter the ratings and characteristics of each breaker. Perform a load flow analysis to determine steady-state conditions. Conduct a short circuit study to determine fault currents and verify if breakers are adequately rated. Compare fault currents to breaker capacities and identify any under-rated breakers. Generate reports detailing findings and recommendations. Review the results with a qualified engineer for accuracy.
