The current transformer and the ammeter do not show the same
Is the pointer of the ammeter clear? As you described, the flow ratio at one time should be 160:1, one 87A, and the current number is 0.54A
From the description, use clamp meter measuring data, current transformer current is one or two times of the only current meter measurement problem, 2.3A measurement 140A, too bad, or find the reason from the table on the right, if you can put photos come to look at the table
