I am playing with the 2nd and 3rd VT’s and having some trouble. Please check me here:-
1.We load them under channel 13 & 14 respectively ( with 1st VT being on channel 0 )
2.We dont need R10 and R11 in place , and
3.We should not be using CT’s in 13 & 14.
4.Additionally, we remove burden input on 13 & 14 ( software )
If so , i am not getting any voltage reading on 2 , nor 3 - when i click to calibrate it wants to default to 120 and immediately goes to zero. I have done a physical check on the actual VT’s with a multi and they are outputting voltage. VT1 is also doing something funny in that it doesnt settle down ( racing up and down then again ).
AM i missing something ?
ps. i don’t have 3phase derived ticked
