I am TTR testing a 9 kVA 480/240V 3-phase transformer and am getting different values for each. Here is what I got:
H1-H2 X1-X2: 1.805
H2-H3 X2-X3: 1.698
H3-H1 X3-X1: 1.580
On a three-phase TTR transformer, all reading would normally be the same, but a Scott-T uses 2-coils to get 3-phases, but how do you hand calculate the expected values?
