Farady Electric 33 kV / 1600kVA oil-immersed transformer successfully passed the complete type test of KEMA Czech laboratory!
This is Farady Electric's second KEMA certificate, following the one for the 33/11 10MVA main transformer. It signifies that the company's products have reached world-class levels in terms of technical performance and quality, laying a solid foundation for entering high-end markets in Europe and the United States!
I. KEMA Certification: The Power Equipment Industry "International Pass"
What is it? KEMA？
KEMA Labs Established in 1927 year Headquartered in the Netherlands, it is Global leader in high-voltage electrical equipment testing. A major part of theInternational Short-circuit Testing Consortium (STL) Core members, After nearly a century of development, KEMA has become one of the most trusted third-party certification bodies in the global power industry.
• Establishment Date： 1927 Year (almost a hundred years old)
• Location of Headquarters: City of Arnhem, Netherlands
• Industry status: International Short-circuit Test Consortium (STL) Core members
• Certification Coverage： IEC International Electrotechnical Commission, CENELEC European Electrotechnical Commission standards
• Global recognition: Used 80 Multiple countries and regions Approval
KEMA Market value of certification
In the power equipment industry, a KEMA certification is hailed as "International Pass". Mandatory access qualifications for high-end markets such as Europe and North America. Major global manufacturers of power equipment such as ABB, Siemens, GE, are all KEMA certified. KEMA Certification is an important endorsement of a products quality.
Industry consensus: No KEMA Certification makes it difficult to open the doors of the high-end electricity markets in Europe and the United States.
II. Short circuit testing: the transformer industry "Adult rites"
Why is short circuit testing the ultimate test?
In all experimental tests for transformers, theShort-circuit Tolerance Test, Recognized The most difficult and risky. The test, known to industry experts as a transformer manufacturers' "Adult rites"。
The rigor of the experiments is reflected in:
| Pilot projects | Technical requirements | The test focuses |
|---|---|---|
| Short circuit current shock | Each phase 3 Once, every time. 0.5 Seconds (about 16 A Zhou Bo) | Mechanical strength of the circle |
| Impedance change control | IEC The amount of change required by the standard < 1% | Structural design stability |
| Dynamic Stability | To withstand huge electric power shocks | Manufacturing process accuracy |
| Thermal Stability | The Test of Extreme Warm Up | Insulation System Reliability |
How high is the failure rate of a short circuit test?
according to KEMA Official statistics (1996-2016 Year):
- The overall failure rate of transformer short circuit tests is about 60%
- About a dozen of them were 5%, Although the product passed the electrical specifications, the crane inspection found internal deformation and still could not obtain certification.
- The main causes of failure include: winding deformation, end rotation, coil indentation, inadequate support of the clamping structure, etc.
What does that mean?:This means that 6 out of every 10 transformers submitted for testing fail! Passing the KEMA short-circuit test is itself the highest affirmation of a company's design capabilities and manufacturing processes.
Farady's performance is outstanding.
The 33kV/1600kVA oil-immersed transformer submitted for testing successfully completed the following tests at the KEMA Czech laboratory:
A full set of routine tests—— Verify the basic performance indicators of the product
Full set of type tests—— These include temperature increase tests, insulation tests, etc.
Short-circuit Tolerance Test—— The most critical test of limits
Lightning shock test—— Verify the resistance of insulation systems to overvoltage
Test results show that the product's performance indicators are excellent, Completely consistent IEC 60076 A series of international standards requirements！
III. IEC Standards: a global technical constitution for power equipment
International standards followed by the tests
This certification is strictly adhered to International Electrotechnical Commission (IEC) A series of standards has been developed:
• IEC 60076-1: General rules for electric transformers
• IEC 60076-3: Insulation levels, dielectric tests and external air gaps
• IEC 60076-5: The ability to withstand short circuits
These criteria are A unified technical language for the global design, manufacture and inspection of power equipment, It has been widely adopted by countries around the world.
IV. What does KEMA certification mean?
For customers and partners:
Quality assurance—— Products pass some of the world's toughest test standards
Safe and secure—— Short-circuit resistance has been tested in real-world situations
International connectivity—— accord with IEC Standards, universally available
Long-term value—— More assured design life and operational reliability
