- This standard specifies the setting calculation principles and methods for large generator transformer relay protection. It is the basis for setting calculations by the design, scientific research, operation, commissioning and manufacturing departments. This standard applies to the capacity range of generators and transformers specified in GB/T 14285-2006, and focuses on the setting calculation principles and methods for relay protection of generators of 300MW and above and transformers of 220kV and above. Reference execution for setting calculations of small-capacity generators and low-voltage transformers.
