RSL

RSL, or Relative State Load, is a measure used mainly in engineering and system management to assess how much demand or stress a system is experiencing compared to its maximum capacity. Think of it like a fuel gauge: an RSL close to 1 indicates the system is operating near its limit, while a lower RSL suggests it has more capacity available. This helps operators monitor system health, anticipate potential issues, and make informed decisions to ensure safe and efficient operation.
