Does anyone have a source for 800A CT’s? I am trying to setup power monitoring at a business I own and we have an 800A high leg delta service. I checked and the mains are single conductor. I see some ECS80 CT’s listed in the options on my home unit but I am having a hard time finding somewhere I can actually buy them.
I did find other CT’s that are not listed in the options here:
and:
The ECSL55800 and ECS80-800 (55mm and 80mm) are Echun CTs. See this post:
Thanks for the info!
Good news is that I found another spot in the chain where they used 2 conductors for each phase. Now my question is this: Do I need to use 6 CT’s or would 3 CT’s with doubling turned on be accurate enough?
Only you can decide if it’s accurate enough. I can say that I have observed as much as 5% difference between cables in a very similar situation.
Thanks, that at least gives me a starting point. I’ll probably do 6 and then see how it goes from there. Thanks for the help!
