Merlin Gerin MV protection guide said:The accuracy-limit factor is the ratio between the accuracy-limit current and the rated
current.
For class P:
5P10 means 5% error for 10 In and 10P15 means 10% error for 15 In,
5P and 10P are the standard accuracy classes for protection CTs,
5 In, 10 In, 15 In, 20 In are the standard accuracy-limit currents.
what is accuracy limit current and what is In ?
