Transformer Routine Tests
Routine transformer tests performed on each completed unit in accordance with the applicable product standard and approved order requirements.
Routine tests verify the manufactured unit's electrical characteristics, insulation withstand, connections, losses, impedance, and functional condition. The exact sequence and report format depend on transformer type, rating, applicable standard, and confirmed project specification.
Test scope and acceptance basis
Routine transformer tests performed on each completed unit in accordance with the applicable product standard and approved order requirements.
Routine tests verify the manufactured unit's electrical characteristics, insulation withstand, connections, losses, impedance, and functional condition. The exact sequence and report format depend on transformer type, rating, applicable standard, and confirmed project specification.

Products Supported by Transformer Routine Tests
The test scope and quality files must match the actual product, rated data, applicable standard, and confirmed order specification.
How the work is controlled
Confirm order, model, rating, serial number, nameplate, drawing revision, and test specification.
Record winding resistance, voltage ratio, vector group, no-load values, load loss, impedance, and other applicable measurements.
Perform applicable withstand tests and verify accessories, controls, alarms, fans, indicators, and wiring.
Review measured values, tolerances, instrument references, signatures, deviations, and final product status.
Project inputs and acceptance basis
| Applicable basis | Product standard and edition, approved data sheet, guaranteed values, tolerances, and agreed deviations. |
|---|---|
| Product identity | Order, model, capacity, voltages, frequency, vector group, serial number, and nameplate data. |
| Test scope | Oil immersed, dry type, compact substation, switchgear, and accessory functions require different applicable items. |
| Witness and report | Witness points, language, report template, measurement units, signatures, photos, and release workflow. |

Technical questions: Transformer Routine Tests
Does Transformer Routine Tests 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 Routine Tests?
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?
Product standard and edition, approved data sheet, guaranteed values, tolerances, and agreed deviations.
What test or quality records can be produced?
Unit-specific routine-test report, Measured values and acceptance limits, Instrument identification where recorded, Nameplate and serial-number linkage, Deviation or retest record if applicable, Authorized review and release
