Oil-filled current transformers (TRA)
Current transformers using oil insulation, featuring Euromek’s proven high-reliability design, ensure accurate and reliable current transformation and measurement. FEATURES
• Voltage rating up to 550 kV
• Primary rated current up to 5000 A
• Products that have passed all types of tests in accordance with international standards
• Seismic design up to 1g
• Class 1 and Class 2 Internal Arc reports compliant with the new IEC 61869-1 Standard GENERAL Euromek’s design, which allows for the use of fewer components, combined with optimized drying and oil impregnation processes, enables easy adaptation to customers’ specific needs.
