Wiring Form 6S Meter As Form 5S

[tmaly1]

Dear Folks,

Is there a way to wire a Form 6S meter to accommodate Form 5S Meter requirements. The Switchgear instrumention available are 2 PT's and 3 CT's, the PT's are connected A-B & B-C while the three CT's are connected in star configuration. We only have Form 6S meter which if I understand correctly only accepts Phase-Neutral output from the PT's.

Is there a way to wire the instrument CT's and PT's cited above to the Form 6S meter without having to re-configure the bus PT's and connect them Phase-Neutral?

Thanks in advance for your feedback and insight.

There is no way to recreate the information about line-neutral voltages that is lost when the PTs are connected line-line.
