Romagnole three-phase pad-mounted transformers are designed and manufactured according to all applicable IEEE standards, from the general definitions and requirements to the test’s specificities. All transformers are oil-immersed (mineral ASTM D3487 Type II or FR3), 65°C temperature rise, designed for usual service conditions per IEEE C57.12.34.
Transformers are DOE 2016 compliant and have short-circuit impedances according to IEEE C57.12.34.
