KEMA Tested Transformers
KEMA test and certification records for applicable transformer projects, including oil-immersed, dry-type, and high-voltage power-transformer evidence.
The available evidence includes 11kV 2500kVA oil-immersed and dry-type transformer KEMA routine, type, and special test records, plus high-voltage KEMA Labs records such as an SFZ-250000kVA 345/34.5kV transformer and a 63MVA 110/10.5kV transformer. For serious buyers, KEMA evidence matters because it helps consultants and utilities judge whether a design family has passed recognized third-party testing beyond an internal factory statement. Each project matches the relevant report, tested object, standard, test program, results, and design relationship to the quoted transformer model.
Published evidence for international transformer projects
These previews are rendered at high resolution from original documents. Registration identity, address, traceability numbers, and signatures are redacted in the public version; complete project files are available during project qualification. Documents that require periodic renewal are still included in the project file set, while public pages show type, standard, scope, and market use instead of fixed document dates.

Clause-by-clause comparison of the tested design and ordered design, including approved deviations.
Products Supported by KEMA Tested Transformers
The test scope and quality files must match the actual product, rated data, applicable standard, and confirmed order specification.
How the work is controlled
Record model, MVA rating, voltages, winding arrangement, cooling, insulation, accessories, and tested configuration.
Check report/certificate number, laboratory, standard and edition, tests performed, results, dates, and tested object.
Compare the ordered transformer with the tested design and document all differences requiring engineering or additional evidence.
Agree which KEMA evidence, routine tests, additional tests, FAT, drawings, and reports form the actual acceptance package.
Project inputs and acceptance basis
| Test record identification | SFZ-250000kVA 345/34.5kV tested model or another exact report-linked model. |
|---|---|
| Ordered transformer | MVA rating, HV/LV/tertiary voltages, impedance, losses, cooling, insulation, taps, accessories, and site conditions. |
| Test requirement | Governing standard, routine/type/special tests, witness points, third-party role, tolerances, and report language. |
| Design comparison | Clause-by-clause comparison of the tested design and ordered design, including approved deviations. |

Technical questions: KEMA Tested Transformers
Does KEMA Tested Transformers 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 KEMA Tested Transformers?
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?
SFZ-250000kVA 345/34.5kV tested model or another exact report-linked model.
What test or quality records can be produced?
Applicable KEMA report/certificate, Tested-object identification, Tested-design-to-order comparison, Approved transformer data sheet, Order-specific test reports, Final acceptance dossier
