Functional Features: Integrated protection functions including overcurrent (50/51), ground protection (50G/51G), differential (87), distance (21), over/under-voltage (27/59), frequency (81), reverse power (32); unique high-impedance fault detection for downed conductor detection; transient ground fault detection (TGFD); flexible load encroachment; routable GOOSE (R-GOOSE) for wide-area protection; phasor measurement unit (synchrophasor) per IEEE C37.118 (2011) and IEC 61850-90-5; fault recording; built-in self-diagnostics; programmable logic.
Application Scenarios: Primary protection and control for feeders on solidly, impedance, or resonant (Petersen coil) grounded systems; bus blocking/interlocking schemes; distribution load shedding; high-speed fault detection for arc flash mitigation; throwover (bus transfer) schemes; backup protection for transmission lines, feeders, and transformers; distributed generation interconnect protection.
Material Composition: Housing in flame-retardant engineering plastic (UL94 V-0); anti-glare polycarbonate front panel; nickel-plated copper alloy terminal blocks; internal FR-4 epoxy glass fiber PCB with conformal coating.
Structural Characteristics: Panel-embedded mounting (1/4 DIN standard); front-panel seal gasket for IP54 (front) protection; rear wiring terminal blocks.
Working Principle: CT/PT signals from the primary system are acquired, converted via A/D, and processed in real time by a DSP. When fault characteristics exceed preset thresholds, the relay drives output contacts to issue trip or alarm signals. IEC 61850 enables high-speed peer-to-peer GOOSE messaging for substation automation.
Usage Notes: Commissioning requires careful setting of protection curves per system coordination study; verify network security configuration for critical infrastructure protection; perform periodic self-test and fault-recorder review.
