2. Core Features

• Ultra-High Measurement Precision: 0.1-class voltage/current accuracy and 0.2-class active power accuracy—meets revenue metering standards (IEC 62053-22) and enables precise power quality analysis (e.g., detecting 0.1% harmonic distortion), critical for grid optimization and equipment protection.
• Comprehensive Power Quality Analysis: Covers harmonics (up to 50th order), voltage flicker (Pst/Plt), unbalance, and transients—identifies hidden power quality issues (e.g., voltage sags causing motor trips) that standard meters miss, reducing equipment downtime by 30%~50%.
• Smart Grid Integration: Native IEC 61850 support (MMS/GOOSE/SV)—seamlessly connects to smart grid systems, enabling real-time data transmission (e.g., GOOSE-based fault alerts) and remote configuration via MMS, complying with modern grid automation requirements.
• Long-Term Data Storage & Trend Analysis: 16GB SSD stores up to 10 years of interval data—supports long-term energy consumption tracking (e.g., seasonal peak demand analysis) and power quality trend identification (e.g., increasing harmonics from new VFD installations).
• Industrial-Grade Durability: IP40 front panel, -25℃~+70℃ operating range, and Level 4 EMC immunity—functions reliably in harsh environments (e.g., outdoor substations, industrial plants with high vibration) without performance degradation.
• User-Friendly Operation: 5-inch sunlight-readable touchscreen and HTTPS web interface—enables on-site parameter configuration (e.g., logging intervals, fault thresholds) and remote monitoring (no on-site PC required); COMTRADE data export simplifies fault analysis.
• Redundant Communication: Dual Gigabit Ethernet ports (IEC 61850/Modbus TCP)—ensures 99.999% communication uptime, critical for remote grid management (e.g., utility SCADA systems) where communication loss could delay fault response.

3. Application Fields

• Power Distribution Utilities: Grid Monitoring & Compliance:
  • LV/MV Substations: Measures voltage/current/power in distribution networks—0.2-class power accuracy supports revenue metering; power quality analysis ensures compliance with grid codes (e.g., IEC 61000-3-2 for harmonics); IEC 61850 integration enables remote substation monitoring via utility SCADA.
  • Grid Fault Diagnosis: Detects voltage sags/swells and transients—COMTRADE fault records help utilities identify fault locations (e.g., downed power lines) and reduce outage restoration time by 20%~30%.
• Renewable Energy Plants: PV/Wind Farm Grid Integration:
  • Solar PV Plants: Monitors power quality of grid-connected PV inverters (e.g., harmonic distortion, voltage flicker)—ensures compliance with IEEE 1547 (grid interconnection standards); active power measurement tracks PV energy yield for performance optimization.
  • Wind Farms: Analyzes voltage unbalance and frequency fluctuations from wind turbine generators—helps balance power output to the grid; long-term data storage supports wind farm efficiency analysis (e.g., energy loss due to grid constraints).
• Industrial Facilities: Power Quality & Energy Optimization:
  • Manufacturing Plants: Identifies power quality issues (e.g., harmonics from welding machines, voltage sags from motor startups)—prevents equipment damage (e.g., VFD failures) and production downtime; energy measurement tracks department-level consumption for cost allocation.
  • Chemical Plants: Monitors power flow in critical process circuits (e.g., reactor cooling systems)—detects abnormal power draw (indicative of equipment degradation) and triggers maintenance alerts; EMC immunity resists interference from chemical pumps and compressors.
• Commercial & Critical Infrastructure: Energy Management & Reliability:
  • Data Centers: Measures power consumption and power quality (e.g., voltage stability) for UPS systems and server racks—ensures stable power supply to critical IT equipment; trend analysis helps optimize data center energy efficiency (e.g., reducing peak demand charges).
  • Hospitals/Airports: Monitors power quality in life support/air traffic control circuits—detects voltage transients that could disrupt sensitive equipment; redundant communication ensures continuous data transmission to facility management systems.
