Sensors based on alternative principles have been introduced as successors to conventional instrument transformers in order to significantly reduce size, increase safety, and to provide greater rating standardization and a wider functionality range.
The voltage sensor is based on a resistive divider. This sensor is non-saturable and linear over the whole measuring range. The output signal is a voltage, which is proportional to the primary voltage.
The voltage sensor KEVA B has been designed to be used as a post insulator but can be used as a stand-alone unit as well.
