Inductive Combined Transformer EJOF

Combined instrument transformers type EJOF are used in high voltage networks within the 24-170kV range. They transform high voltage and high current into standardised values for meters, measuring and protection devices.

The inner construction is similar to that of a current and voltage transformer. The current transformer is located in the head and the voltage transformer in the bottom housing of the combined instrument transformer. The fine graded bushings are inside the insulator.

All combined instrument transformers have either a high-quality porcelain or a high-grade silicone composite insulator. Different creepage distances are available according to the different pollution classes, as specified in the standards.
