Functional Features Full ANSI feeder protection functions. Breaker failure, synchro‑check and four‑shot auto‑reclosing. FlexLogic custom automation logic. Redundant Ethernet for seamless network switch‑over. Oscillography and millisecond event recording.
Application Scenarios Medium‑voltage feeder protection for substations requiring redundant network. Distributed generation interconnection protection. Spare part for IEC61850 upgrade projects.
Performance Parameters Fault response time below 50ms. 64 samples per power cycle. Seamless redundant Ethernet switch‑over. Large event and waveform storage capacity.
Material Composition Flame‑retardant ABS housing with lockable transparent cover. Conformal coated multilayer PCB. Sampling transformers, DSP, relay assemblies, rear screw terminals.
Structural Characteristics Panel‑mount enclosure. Front LCD, keypad and LED indicators. Rear side holds all field terminals. Modular internal boards for acquisition, CPU, relay and communication.
Working Principle Field CT/VT signals go to analog terminals. DSP continuously samples and executes protection logic. Trip outputs activate upon fault detection. Dual Ethernet communicates with SCADA and other IED devices.
Installation Requirements Disconnect all field power and CT/VT loops. Mount unit to cabinet panel. Complete wiring. Restore power, download parameters, test redundant network and I/O loops.
Usage Notes Prohibit CT secondary opening under energized condition. Maintain cabinet ventilation. Anti‑static operation during module replacement. Regular terminal torque inspection.
