The aux CT will be connected to the relay, and Liteyear is correct, the design is essentially for "cheap insurance" to the customer in the case that the CT secondary is opened accidentally (response to multiple previous expereinces). I seemed to incorrectly assume that the CT would have the...
In designing an interposing CT circuit, should a known resistive element be designed into the secondary of the main CT to reduce error? It seems that shorting the main CT secondary through the interposing CT with only the resistance of the wire might result it maximum error from the main CT...
