Medium Voltage First-Fit Current Sensor
PRODUCT DESCRIPTION
Designed for a First-Fit application the NxxxR-xx current sensor is dedicated for installation on the bushing of gas-insulated switchgear in the secondary energy distribution. The design is slim and the holding system can be adapted to different kind of T-connectors. Earthing could be done at the current sensor, or through the shielding of the cable or through the S2 connection inside the IED.
- Passive technology, no active parts are inside, or a power supply is needed
- Standard housings, commonly used in low voltage applications are used, no need for adaptations in switchgear
- Wide range behaviour, one sensor can replace thousands of variants of conventional CT´s
- Easy installation
- High-temperature range
Sensors for retrofit applications on Medium Voltage Switchgear
Split-type Current Sensor
PRODUCT DESCRIPTION
The NxxxT-xx current sensor is dedicated for installation on the cables of gas or insulated switchgear in the primary or secondary energy distribution. The design is split able, which makes it able to put the sensor on an existing cable. Earthing could be done at the current sensor, or through the shielding of the cable or through the S2 connection inside the IED.
PRODUCT ADVANTAGES
- Passive technology, no active parts are inside, or a power supply is needed
- Split-able form factor for retrofit installations
- Easy installation
- Adaptive connection system for earth connection
- High-temperature range
Split-type residual current sensor
PRODUCT DESCRIPTION
The NxxxE-xx current sensor is dedicated for installation on the cables of gas or insulated switchgear in the primary or secondary energy distribution. The design is split able 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 switchgear, where the pole distance of the phases can vary up to 1.5m
PRODUCT ADVANTAGES
- Passive technology, no active parts are inside, or a power supply is needed
- Split-able form factor for Retrofit installations
- Easy installation on existing cables
- High-temperature range
Retrofit Current sensor with correction factors
PRODUCT DESCRIPTION
The NxxxT-0U current sensor is dedicated for installation on the cables of gas or insulated switchgear in the primary or secondary energy distribution. The design is split able, which makes it able to put the sensor on an existing cable. Due to cost-effective construction, the sensor has a very high cost-benefit ratio.
PRODUCT ADVANTAGES
- Passive technology, no active parts are inside, or a power supply is needed
- Split-able form factor for Retrofit installations
- Easy installation on existing cables
- Correction factors for amplitude and phase inaccuracy improve the sensor class
