Transformer Factory Acceptance Test
Factory acceptance testing for transformer and power distribution orders, with agreed witness points, procedures, records, functional checks, and release decisions.
FAT is most effective when planned before production completion. The approved specification, drawings, test plan, guaranteed values, component list, protection logic, report forms, witness arrangements, and acceptance authority should be agreed before the customer or inspector arrives.

Products Supported by Transformer Factory Acceptance Test
The test scope and quality files must match the actual product, rated data, applicable standard, and confirmed order specification.
How the work is controlled
Issue agenda, procedures, acceptance criteria, witness/hold points, equipment status, duration, and responsibilities.
Confirm approved drawings, data sheets, component records, calibration, routine-test results, and open actions.
Perform agreed electrical, mechanical, functional, interlock, alarm, control, visual, and dimensional checks.
Record results, deviations, retests, corrective actions, signatures, document status, and shipment-release conditions.

Technical questions: Transformer Factory Acceptance Test
Does Transformer Factory Acceptance Test apply to every transformer?
Applicability depends on product type, rating, applicable standard, and the order specification. Routine tests normally apply to each unit; type or special tests are confirmed by project.
What is the acceptance basis for Transformer Factory Acceptance Test?
Acceptance should use the approved data sheet, applicable standard and edition, guaranteed values, tolerances, agreed deviations, procedure, and order requirements.
What should be confirmed before the work starts?
Specification, data sheet, GA, wiring, single-line diagram, nameplate, components, deviations, and test plan.
What test or quality records can be produced?
Approved FAT procedure and agenda, Attendance and witness record, Completed test and inspection sheets, Photographs or remote-witness records, Punch-list closure evidence, Signed FAT and release statement
