CURRENT SENSORS
Current sensors for retrofit or first installation applications in medium voltage switchgears
Current sensor for installation on bushings
PRODUCT DESCRIPTION
The ExxxR-xx current sensor is dedicated to installations on the bushing of gas-insulated switchgear on the secondary energy distribution level. With a slim design, the holding system can be adapted to different kinds of T-connectors. Earthing can be done at the current sensor, through the cable's shielding, or through the S2 connection inside the IED (intelligent electronic device).
- Passive technology – no active parts are inside, and no power supply is needed
- Splittable form factor for retrofit installations
- Easy installation on bushings and cables
- Correction factors for amplitude and phase inaccuracy improve the sensor class
- Available as ECO-variant: Initial accuracy class 1, utilizes correction factors for accuracy class improvement
- IP67 protection if needed
Sensors for retrofit applications on Medium Voltage Switchgear
Residual current sensor for retrofit installation in split-core-design
PRODUCT DESCRIPTION
The ExxxE-9L current sensor is dedicated for installation on the cables of a gas or insulated switchgear in the primary or secondary energy distribution. The design is splitable and divided into 3 separate rings, which makes it able to put the sensor on an existing cable. The rings make it possible to install this product inside switchgears, where the pole distance of the phases can vary up to 1.5m.
PRODUCT ADVANTAGES
- Passive technology – no active parts are inside, nor a power supply is needed
- Split-able form factor divided in 3 separate rings, perfect for installation on bigger pole distances
- Easy installation
- High-temperature range

Residual current sensor for retrofit installation in split-core-design with correction factors
PRODUCT DESCRIPTION
The ExxxE-xx current sensor is dedicated to installation on the cables of gas—or air-insulated switchgear in the primary or secondary energy distribution. The design is splittable, making it easy to put the sensor on an existing cable. Due to its cost-effective construction, the sensor has a very high cost-benefit ratio.
PRODUCT ADVANTAGES
- Passive technology – no active parts are inside, nor power supply is needed
- Splitable form factor for retrofit installations
- Easy installation on bushings and cables
- Big inner diameter for installation on 3 cables
- Correction factors for amplitude and phase inaccuracy improve the sensor class
