CSN® Current Sensors

CSN® Current Sensors are used for current measurement in control and protection systems in power transmission links (AC and DC applications). The CSN® type Current Sensors are based on highaccuracy resistive sensors (shunt) respectively iron free cores (CSN® AirCoil). There are selfsupporting structures available where the CSN® Current Sensor is mounted on top of a composite insulator, as well as variants in which the CSN® Current Sensor will be mounted hanging in the busbar. Schniewindt has implemented CSN® Current Sensors for nominal currents of up to 5 kADC at system voltages of 800 kVDC, which have been successfully typetested. Also for the precise measurement of small currents (1 to 10 A), such as transient currents in capacitor banks, Schniewindt offers appropriate solutions. All of our CSN® Current Sensors are individually designed according to customer requirements.
