  • Application

    Thesystem is used to apply high current on current transformer and measure itserror, suitable to use on substations site.  

    Thesystem is designed for sorts of current transformers such as oil-filled CT, SF6 CT, CTbuilt-in GIS, etc.

    Features

    l  Direct measurement: directlyapply rated current to several KA on primary side of current transformer undertest.

    l  No need of connecting cables:since high current device, voltage regulator, and standard current transformercombine to one modular. The connecting cables between are avoided.

    l  High lifting capability: thehigh current device is able to lift 3~10m

    l  Easy transportation: thetotal height is less than 2.5mwhile transportation. It is able to go across bridges and tunnels.
