TE’s RSTI screened separable connector fits 630/1250A bushings type “C” as specified by EN 50180 and EN 50181. Our capacitive voltage sensors for screened separable connectors are suitable for measurement and protection applications. They must be connected to meters and relays of new generation.

The capacitive voltage sensors are passive medium voltage instrument transformers based on capacitive voltage divider concept. They require no external power supply or battery. They provide inherent safety due to their capacitive divider concept, which has galvanic isolation from high voltage.

The capacitive voltage sensors are calibrated in the factory and no need for any further adjustment on site.

They are suitable for both new installations and retrofit solutions in medium voltage networks.


  • High accuracy class suitable for metering, measuring, and signaling tasks
  • Tested according to the latest IEC-61869-11 and CENELEC HD629.1 S2
  • Compact design using shortened cone for asymmetric T-connector
  • Total galvanic isolation from the high voltage
  • Capacitive voltage sensors can act as coupling capacitance for on-site PD monitoring
  • No need for auxiliary power supply
  • Easy installation suitable for retrofit on medium voltage network
