the site measured knee point voltage of protection class CTs should be greater than rated knee point voltage? what about meetering class CTs. Should it be below the rated knee point voltage?
1468transformer spections :: input voltage 0-110-230v; output volage 0-10-12-14v; amp=3A using CRNO CORE, capcaity=50VA primary turns = ? ; secondry turns =?
Bhel,
