Primary wounds CTs 5 – 200 A

Low voltage current transformer

IEC/EN 60044-1

PSW 55

PSW 55
  • Using window type CTs only lower power outputs and accuracy classes can be achieved at low CT ratios. There fore the use of primary wound CTs is recommended if higher power outputs and accuracy classes are needed in case of low CT ratios. In primary wound CTs the primary conductor is wounded serealfineson the magnetic core of the CT.
