Indoor voltage sensors KEVA B

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 sensor KEVA B has been designed to be used as a post insulator but can be used as a stand-alone unit as well.  
 
Product scope
Two sensor designes suitable for all applications up to 24 kV
Accuracy class 0.5/3P for voltage measurement
Cable connector type, shielded RJ-45 Cat. 6, fully compatible with ABB Relion® product family IEDs, without the need for any connector adaptation
 
Application
Primary and secondary MV air insulated switchgear (AIS),
Original Equipment Manufacturer (OEM)
