Oil Type Inductive Voltage Transformers (TRE)

Euromek inductive voltage transformers are developed for voltage measurement, protection, synchronization, and power quality applications in high-voltage networks.

The magnetic core and winding structure are evaluated according to grid conditions, accuracy expectations, and project specifications. This approach enables the provision of technical solutions tailored to different site requirements.

Key Features
• Maximum operating voltage up to 245 kV
• Oil-impregnated paper insulation system
• Design and testing processes in compliance with international standards
• Seismic design option up to 1g
• Secondary configurations suitable for measurement and protection applications
