WebProtection class CT’s are assumed to be able to supply 20 times its rated secondary current to the relay. That means for a 5 amp rated secondary the CT must be able to supply 100 Amps of current, and for a 1 amp rated secondary the CT must be able to supply 20 Amps of current. The operating principals of CT’s are specified in a format such as this. WebThe CT ratio is the ratio of primary current input to secondary current output at full load. For example, a CT with a ratio of 300:5 is rated for 300 primary amps at full load and will produce 5 amps of secondary current when 300 amps flow through the primary. If the primary current changes the secondary current output will change accordingly.
