Testing and FAT
Factory testing and FAT support for transformers, medium voltage switchgear and low voltage switchgear before shipment.
Verify key electrical tests, functional checks, inspection items and required documents before dispatch. You can arrange witness FAT, remote FAT or test report review to match your project requirements.

Check Every Detail Before Shipment
Look over the test setup, equipment details, nameplates, wiring, accessories and packing condition with your own eyes. You can ask for the full photo set whenever you need it for FAT review, incoming inspection or project sign-off.
Not Sure Which Tests Your Project Needs?
Send us your specification or inspection list. We'll confirm the test items, the FAT type and the documents you'll receive before production wraps up, so you decide what to witness on site, what to review remotely and what gets recorded for your file.
Routine, Type, Special and FAT
Not every project needs the same test level. We help you work out whether routine tests, type test documents, special tests or FAT are needed for your specification before shipment.
Send us your spec
We'll confirm the test level and documents your project needs, no guesswork on your side.
Routine Test
Basic factory tests before delivery, checking electrical performance, insulation, wiring and mechanical operation.
Used For
Standard pre-shipment inspection on every unit.
Type Test
Test documents that verify the product design performance. Not usually repeated for every unit.
Used For
Tender review, consultant approval and utility projects.
Special Test
Extra tests based on your project specification or site conditions.
Used For
Temperature rise, partial discharge, noise, internal arc or oil tests.
FAT / Witness Test
A full factory test review before shipment, covering key tests, functions, documents and final condition.
Used For
On-site witness, remote FAT and third-party inspection.
Testing Coverage for Transformers and Switchgear
Each product type has its own electrical, mechanical, functional and document checks. Here's what gets covered for transformers, MV switchgear and LV switchgear before shipment.
Applicable Products
Oil-immersed transformers and dry type transformers.
Key Test Items
- Winding resistance
- Voltage ratio
- Vector group
- Insulation resistance
- Applied voltage withstand
- Induced voltage withstand
- No-load loss
- Load loss
For oil-immersed units, oil dielectric strength and leakage inspection can be added on request. For dry type units, partial discharge, temperature rise or noise tests can be arranged to match your specification.
Before anything ships, you get to see whether the rating, voltage ratio, vector group, insulation, loss values and final condition all line up with your spec.
Records You Receive
Applicable Products
Medium voltage switchgear and low voltage switchgear.
Key Test Items
- Visual inspection
- Dimension check
- Mechanical operation
- Interlock function
- Insulation resistance
- Power frequency withstand
- Main circuit resistance
- Secondary wiring check
- Protection relay function
- Meter and signal check
For low voltage panels, ATS logic, MCC control loops and APFC step control can be checked according to your panel design.
Before delivery, you get to see the cabinet build, breaker operation, interlock logic, wiring, protection functions, control logic and metering signals all checked over.

How Our FAT Process Works
A clear FAT process lets you review the test scope, witness key functions, check the documents and confirm the equipment is ready before it ships. Here's how each stage runs.
Confirm FAT Scope
Before anything is scheduled, we go through the product type, your specification, drawings, test items, witness method and the documents you need. You walk away knowing exactly what will be tested, what you'll witness and what gets recorded.
Prepare FAT Procedure
We build the FAT checklist, test plan, drawing list, inspection items and acceptance criteria around the scope we agreed. You see how the FAT will run and which items get reviewed, before anyone shows up.
Complete Internal Pre-check
Ahead of the formal FAT, we run our own check on equipment readiness, wiring, mechanical operation, test setup and documents. By the time you witness it, the equipment is already prepared and there are no surprises on the day.
Conduct FAT and Witness Test
You can join on site, watch remotely over video, or send a third-party inspector. Key electrical tests, functional checks, mechanical operation, wiring and visual inspection are all reviewed together, so you see the key functions, results and final condition firsthand.
Record Issues and Corrective Actions
Anything flagged during FAT gets logged with photos, notes and the corrective action taken. Where needed, we arrange a retest or re-check, so you can see exactly how each point was handled before sign-off.
Issue FAT Report and Release for Shipment
Once FAT is done, you receive the FAT report, test records, inspection checklist, photos, videos and the rest of the document package. You review the equipment, documents, accessories and packing readiness before giving the go-ahead to ship.
Test Reports and Documents for Project Approval
After testing or FAT, you get the reports and records your project needs for review, consultant approval, utility submission and shipment release. The exact set depends on your product type, test scope and specification.
