calculating the ct ratings depend on the load either motor circuit or transformer circuit. for example if we have a motor which full load current is 160A then we need a ct 200A/1A or near.Mean that primary current is 200A and secondary current is 1A which is usually use for measuring the motor current on running condition. Because measuring instruments are design for low current inputs mean that 1A is equal to 200A and when motor running on 100A then its equal to 0.5A but measuring device configure it to 100A on display.
