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 sensors KEVA C have been designed as easy replacement of originally used insulating plugs in the cable T-connectors. Due to their compact size and optimized design sensors can be used for retrofit purposes as well as in new installations.
