Measuring a CT Ratio at Different Current
Magnitudes
Example of a sequence of five states to measure the ratio of a current
transformer. To do so, different current amplitudes (5%, 20%, 50%, 100% and
120% of nominal value) are injected into the CT, and the CT’s secondary current
is measured at

.

current magnitudes
Parameters of the states 1 ... 5
Each of the five states injects a current with a different magnitude into the CT’s
primary winding. There is no trigger specified, so each state runs exactly 2s.
