Transformer Demand Factor and Diversity Factor Explained
Release Time: 2026-09-20
Demand factor is maximum demand divided by total connected load for the same group. Diversity factor is the sum of individual maximum demands divided by the maximum coincident demand of the combined system. They answer different questions and must not be swapped or multiplied without a defined load model. This guide gives project engineers, EPC teams and buyers a practical way to define inputs, compare options and document the final decision. It focuses on the search task behind transformer demand factor โดยไม่แทนที่การศึกษาที่ได้รับการอนุมัติ, กฎระเบียบท้องถิ่น, แบบของผู้ผลิต หรือดุลพินิจทางวิศวกรรมที่ผ่านการรับรอง.

Connected Load
Connected Load must be defined from the approved design basis rather than inferred from a product family name. For transformer demand factor, record the source document, operating case and boundary to which this item applies. This prevents a correct value from being used in the wrong part of the system.
Individual Maximum Demand must be defined from the approved design basis rather than inferred from a product family name. For transformer demand factor, record the source document, operating case and boundary to which this item applies. This prevents a correct value from being used in the wrong part of the system.
Coincident Maximum Demand must be defined from the approved design basis rather than inferred from a product family name. For transformer demand factor, record the source document, operating case and boundary to which this item applies. This prevents a correct value from being used in the wrong part of the system.

Diversity Factor must be defined from the approved design basis rather than inferred from a product family name. For transformer demand factor, record the source document, operating case and boundary to which this item applies. This prevents a correct value from being used in the wrong part of the system.
Load Profile must be defined from the approved design basis rather than inferred from a product family name. For transformer demand factor, record the source document, operating case and boundary to which this item applies. This prevents a correct value from being used in the wrong part of the system.
Three process areas each peak at 300 kW, so their individual peaks total 900 kW. If the measured or modeled coincident facility peak is 720 kW, diversity factor is 900/720 = 1.25. If connected load is 1,200 kW, the facility demand factor is 720/1,200 = 0.60.

Demand factor is maximum demand divided by total connected load for the same group. Diversity factor is the sum of individual maximum demands divided by the maximum coincident demand of the combined system. They answer different questions and must not be swapped or multiplied without a defined load model. A defensible project result connects the chosen rating or arrangement to traceable inputs, credible operating scenarios, coordinated equipment and evidence that can be verified before energization. That record is more valuable than a generic rule because it remains understandable when the system changes.
