How to fix ratings to substation?

To fix ratings to a substation, first, ensure that all equipment meets the required design specifications and operational standards. Conduct a thorough assessment of the existing infrastructure to identify any discrepancies or deficiencies. Based on this evaluation, implement necessary upgrades or replacements of components such as Transformers, circuit breakers, and protection systems. Finally, ensure compliance with relevant regulations and standards, and document the ratings clearly on all equipment for future reference.
