Transformer Inspection & Quality Assurance
Independent Engineering Oversight — From Factory Floor to Final Delivery
Our Inspection & QA Services
Pre-Production Review
Review technical specifications, approved drawings, BOM, testing requirements, and applicable standards before production begins.
Production Monitoring
On-site monitoring of key manufacturing processes, production progress, and critical quality checkpoints.
Factory Inspection
Inspect workmanship, dimensions, nameplates, accessories, coatings, wiring, and other project-specific requirements.
FAT Witnessing
Witness and verify Factory Acceptance Tests, testing procedures, equipment, and test results.
Documentation Review
Review test reports, certificates, drawings, inspection records, and final project documentation.
Pre-Shipment Inspection
Final inspection of finished products, packing, protection, loading arrangements, and shipment readiness.
Your Factory. Our Engineering Oversight.
Already have a transformer manufacturer in China?
No problem. Our Inspection & QA services are available independently from transformer sourcing.
We can visit multiple factories, compare their capabilities, monitor production, witness FAT, review documentation, and provide independent inspection reports before shipment.
Independent technical evaluation
On-site inspection & FAT witnessing
Detailed reporting & follow-up
Non-conformance tracking
Pre-shipment inspection
You choose the factory. We provide the engineering oversight.
Our QA Process
FAT & Testing
We can witness and verify routine, type, and special tests as required by the applicable standards and project specifications.
Typical testing may include:
Oil Dielectric Testing
No-Load Loss & Excitation Current
Functional Checks of Accessories
Load Loss & Impedance
Temperature-Rise Test, where required
Applied Voltage Test
Sound-Level Test, where required
Induced Voltage Test
Other Project-Specific Tests
Insulation Resistance
The actual FAT scope is determined by the transformer type, approved specifications, purchase requirements, and applicable standards.
Standards & Compliance
We review whether the transformer, testing procedures, acceptance criteria, and documentation are aligned with the applicable project requirements.
Our team is familiar with major international transformer standards and project requirements, including:
