Current protection relay PCS-9613

phase asymmetryover-currentover-voltage

Product overview
The PCS-9613 is a current differential (87L) and multi-stage overcurrent protection relay for distribution feeder lines. It integrates protection, control and monitoring functions with three-pole auto-reclosing and supports solidly grounded, impedance grounded, Peterson coil grounded and ungrounded systems. The relay fully supports IEC 61850 including GOOSE and is intended for modern digital substations.

Protection and Control

• Current differential protection (87L)
• Six-stage phase overcurrent protection (50P/51P/67P)
• Six-stage zero-sequence overcurrent protection (50G/51G/67G)
• Negative-sequence overcurrent protection (46)
• Broken-conductor detection using I2/I1 ratio (46BC)
• Breaker-failure protection (50BF)
• Thermal overload protection (49)
• Undervoltage/Overvoltage protection (27/59)
• Switch-on-to-fault (SOTF) logic
• Synchronism check (25)
• Three-pole auto-reclosing (79)
• Mechanical protection and remote control/measurement
• Voltage and current drift auto-adjustment

Communication

• Up to four 10Base-T/100Base-TX (RJ45) ports or two 100Base-FX ports
• IEC 61850-8-1 MMS and GOOSE support
• IEC 60870-5-103 over TCP/IP and DNP 3.0
• Two RS-485 rear ports with IEC 60870-5-103; additional RS-485 for clock sync
• RS-232 rear port for printer; front faceplate RJ45 for testing and setting
• Clock synchronization via pulse, IRIG-B and SNTP

Monitoring and Metering

• Tripping circuit supervision
• CT and VT failure detection logic
• Synchro-check voltage failure supervision
• Self-diagnostics and fault recorder
• 1024 SOE (sequence of events) entries including trips, alarms and operator actions
• 64 oscillograms compatible with COMTRADE format
