Current Transformers

Bowdens supply cast resin CTs either split core or solid core with a turns ratio of 60:1. With a standard i.d. of 90mm they are designed to fit around the H.V. cable using the clamp provided. A special double wound split core CT is available for our NB range.

Bowdens also supply the band CT which is an open-ended, split core CT wound on a flexible stainless steel core, and can be made to various standard lengths. Standard nominal i.d. dimensions are: 50mm for single phases in a cable box. 120mm standard Earth fault applications. 220mm for extending around three single phase conductors to give out-of-balance earth fault. 380mm for larger separation around three single phase conductors.
