Source of CT Error
(OP)
What is the consensus on where CT error originates? Is it in the turns ratio not being exactly as given, or would you say it is the phase lag?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Scottf may be along to add something since he does this for a living.
But it's not like people are forming opinions. The sources of error are pretty well known and understood. A few minutes of Googling will turn up more references.

Please pay attention on the Electricpete's "Ideal CT".
You havent it., becouse CT is trafo include iron with losses.
BTW, why 1%, for the meas you have core 0.2 class too.
I don't know , maybe with new tecnologies possible build today ideal CT, but what will price.

I don't remeber exactly this number, but possible with high level of test eq. check/write down meas point of CT.
New meters are include up to 8( maybe more) correction points for the CT ratio and angle errors.
If possible say, that now it's 0.5 class CT, I don't know. not sure. And take in account , you need provide this procedure for each phase.
