Example: The directional ground fault protection is ANSI 67N/67NC. It uses residual voltage Vr as a polarization value.
1A/5A Current Transformers Installation Function 1 Connect Sepam™ to any standard 1A or 5A CT. Schneider Electric offers a range of current transformers to measure primary currents from 50 A to 2500 A. Contact a Schneider Electric representative for more information. Current Transformer Sizing Current transformers should be large enough to minimize saturation. CTs should be selected per ANSI C37.110. This can be critical for high X/R systems with generators larger than 2MW.

Communications Wiring Biasing the Communications Link Installation To ensure reliable communications, you must bias the POWERLOGIC communications link (if biasing is not in the system master nor an interfacing RS232/485 converter). Use a Multipoint Communications Adapter (MCA-485) biasing device. Place the adapter between the first device on the link and the communications port of the PC.
Installation Communications Wiring Terminating the Communications Link To ensure reliable communications, terminate the last device on a POWERLOGIC communications link. The illustration below shows MCT-485 terminator placement when the final device on the link is a POWERLOGIC device.
