Toroidal CT
Toroidal CT
(OP)
Does it matter if the primary conductor carrying the current is not positioned at centre of the toroidal CT? will it introduce any errors due to asymmetrical flux linkage?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Toroidal CT

As a very general statement...the higher the primary current the more important it is to have the primary conductor centered. A general rule of thumb is that at ~3000A and below it is not so important, but there are plenty of exceptions to that.

The positioning of the primary conductor and the proximity of the return conductor can most definitely be an issue with CT performance. For higher current applications, it is common for us CT manufacturers to use special secondary winding designs/shielding to mitigate the effects.
