The phase comparison tripping scheme menu provides the main setup for the phase comparison relay.
• 87PC SCHEME SELECT: Selects the phase comparison element scheme logic as follows:
– 2TL-TR-SPC-2FC: two-terminal line, permissive tripping, single phase comparison, two frequency channel.
– 2TL-BL-SPC-2FC: two-terminal line, blocking scheme, single phase comparison, two frequency channel.
– 2TL-UB-DPC-2FC: two-terminal line, unblocking, dual phase comparison, two frequency channel (FSK PLC only);
scheme cannot be used for breaker-and-a-half applications.
– 2TL-TR-DPC-3FC:two-terminal line, permissive tripping, dual phase comparison, three frequency channel.
– 2TL-BL-DPC-3FC: three-terminal line, blocking scheme, dual phase comparison, three frequency channel.
