Our Raychem RSTI Separable Connectors with Voltage Sensor are designed to increase network transparency and support the implementation of smart grids.
Our Raychem RSTI Separable Connectors with Voltage Sensor is the new generation of screened separable connectors. The separable connector with voltage sensor fits 630/1250A bushings type C as specified by EN 50180 and EN 50181 and is suitable for both new and retrofit installations up to 24 kV.
In conjunction with the new generation of Intelligent Electronic Devices (IEDs), the voltage sensor provides a measuring signal for grid management applications like monitoring, power quality, protection or metering, as well as asset management applications, like PD monitoring.
The capacitive voltage divider concept is used in the voltage sensor technology for passive medium voltage instrument transformers.
This concept provides intrinsic safety and protection advantages for the operation of sensors in power networks due to the galvanic isolation from high voltage. It also provides an appropriate signal for on-site partial discharge monitoring.
In addition, the compact design provides complete integration within the smart separable connector, as well as full encapsulation through a grounded and conductive outer screen.
Very compact design to fit easily in compact switchgears
High accuracy over a wide temperature range
High accuracy on higher harmonics for reliable power quality applications
Type-tested according to both IEC 61869-11 and CENELEC HD 629.1 S2
Inherent safety thanks to total galvanic isolation from high voltage
Simple connection as no auxiliary power supply is needed due to passive components
Factory-calibrated thus no need for on-site calibration
