We measure high voltage for you

using instrument transformers for both outdoor and indoor applications, special transformers, sensors and power transformers

 

Insulation voltage 25 kV Test voltage 50 kV Test impulse voltage 125 kV Nominal primary current 100 – 400 A Overcurrent class Ith/Idyn 16/40 кА Nominal frequency 50 Hz Nominal secondary current 1 or 5 A Power 2 VA Accuracy class 2% Overcurrent factor >5 Weight 8,5 kg drawing [ZIP, 86kB] in DXF format

Current sensor CSO 25 is designed for outdoor networks of 22 kV. Sensor is suitable for protection puposes or signalling. Creepage distance corresponds to highest voltage 25 kV in cases of exceptional pollution severity (31mm/ 1 kV).

Sensor comply with requirements of standards ČSN EN 60660 and IEC 60273 for post insulator JO2-145, specified failing load 2000N. Current sensor fulfilled all the tests according to the ČSN EN 60044-1.

It is possible to consult other technical parameters with the producer.
