Medium-voltage instrument transformers
Current sensor
CSO 38
CSO 38 sensor is a current transformer load is less than 2 VA. The secondary current is 1 A. The output cable length 12 m (length can be customized), the outer insulation is from silicone rubber. The accuracy of conversion depends on the required load.
The sensor is designed for outdoor environments with the highest pollution (ie. 31 mm/kV to 38.5 kV).
Current sensor complies with IEC 60044-1 and GOST 15 150 for T1 and UCHL1.
Other technical parameters can be consulted with the manufacturer.
