APPENDIX
A1 CT/VT Connection Diagrams
Please note that there is an option on the Settings/Input page to invert the CT Polarity
(see screen shot clip below). This option is the equivalent of swapping the connections
in the connection diagrams below at the HI and LO terminals for each CT input, that is,
swapping 11 and 12 (IA), 13 and 14 (IB), and 15 and 16 (IC). The effect is a 180
degree phase shift in the current signals.
Please note that when viewing the following wiring diagrams there is no need for
connection to multiple devices using the same CTs. Also, Bus 1 can be considered
the generator (CTs and PTs) and the Bus 2 the bus (PTs only). For synchronizing,
you can connect to just one phase.
