    Tips: What causes the current transformer to burn out?

    • Secondary open circuit of the current transformer produces high voltage to burn out the current transformer.
    • Long-term use of the current transformer makes the insulation aging, local breakdown or discharge occurs and overvoltage is thereof produced, thus burning out the current transformer.
    • Long-term overload operation makes the current transformer to give out heat, it is thereof burned out.
    • The aluminum contact surface of current transformer’s primary connection is seriously oxidized, which results in large contact resistance. The contact resistance gives out heats and burns out the current transformer.
