Small transformers rated from 25 kVA up to 2,500 kVA.
The standard covers power transformers up to 1000 kV, detailing the requirements for: iec 60076-5
If a transformer undergoes physical testing, it must pass a strict battery of diagnostic checks to be certified compliant. It fails if any of the following conditions occur: Small transformers rated from 25 kVA up to 2,500 kVA
While IEC 60076-5 is the benchmark for much of the world (Europe, Middle East, Africa, Asia), North America primarily operates under and IEEE C57.12.90 standards. iec 60076-5
