Passive Current transformers

Low space requirements combined with outstanding performance

REO current transformers distinguish themselves primarily due to their low space requirements, excellent linearity, short response times and their low iron und hysteresis losses.

The current transformer series are available in a range up to 150 kHz and, as a result of the testing that has previously been performed and is carried out in the manufacturing process, whether that is vacuum casting, partial discharge measurement or high-voltage testing, achieve a high level of reliability and are perfectly adapted to the respective place of use.

  • Series IE modular

    closed-loop current transformers

    Series IE modular
    • Primary rated current: 500 - 2500 A
    • Umgebungstemperatur: -25... +70 °C
    • Frequency range: 50... -400 Hz

    In the case of bushing-type current transformers, the customer’s primary wire is pushed
    through the current transformer opening in the housing. The push-through opening depends
    on the size of the primary current.
    Wound primary type current transformers have a primary winding and a secondary winding.
    Both windings are applied on the closed toroidal core and are isolated from each other by
    insulation. This principle applies mainly where primary currents are small. Low-voltage current
    transformers for the proportional transformation of large currents to directly measurable
    smaller current values.
