Abstract :
In the distribution networks, it is required to develop small and compact voltage sensor and current sensor for compact and digital switchgear. Newly developed sensors adopt rogowski coil for current sensing, and resistive voltage divider for voltage sensing. The sensing characteristics and reliabilities were improved compared to conventional ones. In the near future, these voltage and current sensing apparatus will be widely used with electronic protection units for the distribution switchgear.
