Current instrument transformers

Inductive Current Transformer

Oil-paper insulated outdoor current transformers are used in high voltage networks. They transform high current into standardised values for meters, measuring and protection devices.

The active part of the current transformer is located in the head housing. The high voltage insulation is based on oil-paper technology. 

The expansion bellows made from stainless steel is located above the head housing of the current transformer. This unit acts as volume compensation for the oil in case of temperature variations. The oil level is indicated by a mechanical system in the window of the bellows cover.

All metal housings and flanges are made from a special aluminium alloy. These parts can be colour coated on request.

All current 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.
