Terramodel layer name length9/18/2023 ![]() ![]() During normal operating conditions as the vector sum of three-phase current i.e. – Secondary CBCT is connected to Earth Fault Relay. This type of current transformer is normally used for earth fault protection for low and medium-voltage systems. Core Balance Current Transformer or CBCT is a ring-type current transformer through the center of which a three-core cable or three single-core cables of a three-phase system passes. So that it measures the unbalance current in the 3 phase system. CBCT in other words called Core balance CT which is placed over the cable OD or all covering all 3 phase bus or cable. – Normal CT is used to measure current in any particular corner phase. – Anyone can tell me What is the function of CBCT? Your CTs star point however must be pointing towards T/F or away from it. Just input the data of ur transformer and relay all do the rest. – No need to do anything in the numerical relay. – Don’t need to reverse the connection of CT? – If I had transformer YNd11 and want to connect differential Protection is the CT on Primary should connect in Delta and CT on Secondary should connect in Star when I use Numerical relay or not? Take a look at some of our problem-solving discussions ![]()
