Sigma LV Current Transformers(CT) can convert the primarry current which is from 20A upto 5000A in the requested power and accuracy value into the secondary current which is 1 or 5A value. Sigma CTs are produced in 9 different sizes according to TS 620 EN 60044-1 standards for different busbar dimensions. Sigma CTs can be produced with sealed by Industry and commerce Ministry When requested
Before Production, the cores are controlled and clasified according to the results
The insulation resistance between Primary and secondary which is requested in TS 620 EN 60044-1 as 3 kV is 7 kV in SİGMA Current transformers
