Transformers - Rule 15-6

Rule ID: Rule 15-6
Rule Description: Transformer efficiency reported in User RMR equals Table 8.4.4
Rule Assertion: User RMR = expected value
Appendix G Section: Transformers
Appendix G Section Reference: Table G3.1 15. Distribution Transformers
Data Lookup: Table 8.4.4
Evaluation Context: Each Data Element
Applicability Checks:

1. Transformer is DRY_TYPE
2. U_RMR transformer capacity is within range of Table 8.4.4

Manual Checks: None

Rule Logic:

• For each transformer _user_transformer in U_RMR.transformers:
  • Get maximum regulated capacity: if user_transformer.phase == SINGLE_PHASE: _max_capacity_limit = 333.0 else if user_transformer.phase == THREE_PHASE: _max_capacity_limit = 1000.0
  • Applicability Check 1: _user_transformer.type == DRY_TYPE
  • Applicability Check 2: _user_transformer.capacity >= 15.0 and _user_transformer.capacity <= _max_capacity_limit:
  • Get required User transformer efficiency: required_user_transformer_efficiency = data_lookup(table_8_4_4, _user_transformer.capacity, _user_transformer.phase)
  • Rule Assertion: user_transformer.efficiency == required_user_transformer_efficiency
