FAQs
What is the difference vs distribution transformers?
Power transformers cover higher MVA and higher HV levels (e.g., 66–245 kV) and typically use OLTC/ONAF/ODAF.
50 Hz or 60 Hz?
Both are available; confirm grid frequency early in the RFQ.
Do you supply ANSI/IEEE designs?
Yes—IEC 60076 as standard; ANSI/IEEE C57 on request.
Which tests are performed?
Routine tests per IEC 60076; type/special tests on request. FAT/SAT support included.
