Q1. How to do ct sizing ?
Ans. 
CT sizing is done by considering the primary current, burden, and accuracy class of the CT.
• Determine the primary current of the system

• Calculate the burden of the CT

• Select the accuracy class of the CT

• Use the formula: CT rating = primary current x burden / (accuracy class x 100)

• Example: For a 400A primary current, 5VA burden, and 0.5 accuracy class, CT rating = 400 x 5 / (0.5 x 100) = 40A
