Indoor voltage sensors KEVA C

Electronic instrument transformers (Sensors) offer the voltage measurements for the protection and monitoring of medium voltage power systems up to 24 kV.

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.
