Wika current transformer for Substation

The substations are where the voltages are increased to high values by using step up transformers, and after the transmission, they are again stepped down for distribution. In addition to changing the voltages the substations have, a variety of protective devices like circuit breakers and fuses are present to protect the distribution networks.

  • Difference Between Current Transformer (CT) Potential

    Definition of Current Transformer. A current transformer is a device which is used for the transformation of current at a higher value to a lower value with respect to the earth potential. It is used with the AC instruments for measuring the high value of current. The line current is too high, and it is very difficult to measure them directly.
