I have 2 protective relays (one is an O/C and the other in only a resisdual Wattmetric protection used in case of Petersen Coil earthed system).I use the same CTs for the 3 phases O/C protection and the Summation method of these 3 CTs to supply the residual input of the other relay. Is there a special approach to dimension the CTs and especially to Know the maximum burden.
Thanks in advance for your information.
