GMR-Based Intelligent Magnetic Field Monitoring Solution：
This product delivers an intelligent magnetic field monitoring solution based on Giant Magnetoresistance (GMR) technology, comprising a 3-axis GMR sensor array and a global lifecycle management platform. Designed specifically for health management of critical grid assets such as power reactors, it enables:
1.Real-time 3D magnetic flux mapping (±1% accuracy)
2.Anomaly early-warning via edge intelligence
3.Full lifecycle asset analytics
Our Advantage:
1.Technical Highlights of 3D Magnetic Field Sensing Unit
1.1 High-Precision 3D Sensing
Employs orthogonal GMR sensor array (X/Y/Z-axis spacing ≤3mm) for spatial vector acquisition
Accuracy: ±0.5% FS, Resolution: 16-bit, Bandwidth: 50Hz-250Hz
Captures both steady-state & transient harmonics (complies with IEEE 519)
1.2 High-Sensitivity Fault Detection
Algorithm: Moving Average (N=5) + t-test confidence interval
Metrics: Field deviation (δ) & dispersion (D)
Early Warning Trigger: D > 5S → detects ≤5-turn inter-turn shorts in <1s
1.3 Robust Data Acquisition
2kS/s sampling via hardware timer (Tim3)
LoRa wireless transmission (ISM band) with dual-output:
▶ Hexadecimal data packets
▶ Plain-text (12 key params: Max field, variance, peak dispersion, etc.)
1.4 Non-Invasive Deployment
Live-line installable (no equipment modification)
EMI immunity: -20°C to +65°C stable operation
Commissioning time: 1/3 of conventional solutions
2. Global Online Monitoring Platform
2.1 Multi-Protocol Global Access
Supports MQTT/HTTP/Modbus
Sub-second data sync for worldwide device clusters
2.2 3D Visualization & Real-Time Monitoring
Dynamic 3D flux cloud rendering:
▶ Rotate/slice views & anomaly highlighting
Multi-dimensional analytics:
▶ Real-time X/Y/Z waveforms
▶ Historical trends & threshold dashboards
▶ Cross-device benchmarking
2.3 Intelligent Alerts & Remote Control
Tiered alarms:
STATA：
Warning: 20% baseline deviation → SMS/email
Critical: Field mutation rate > setpoint → audible/visual alerts
Remote configuration:
▶ Adjust sampling rates/alarm rules/LoRa channels
▶ Batch command deployment
2.4 Full Lifecycle Management
Digital twin integration:
▶ Asset registry (location/maintenance logs)
▶ Time-series database (1+ year retention)
Predictive maintenance:
▶ Edge-cloud analytics reduce fault location time from 4hr → 15min
3. Platform-Device Synergy Advantages
Global Device Centralized Management
Worldwide asset tracking: Geographic mapping with real-time status (online/alarm stats)
Multi-site cluster monitoring: Supports cross-timezone grid operations (e.g., concurrent management of Asia/EU substations)
Edge-Cloud Collaborative Efficiency
50% faster data processing vs. pure-cloud solutions
10,000+ device concurrency with load balancing

Application | Critical Monitoring Targets |
Substation dry-type reactors | Inter-turn shorts, Core saturation |
Transmission line equipment | Fault current limiter degradation |
Industrial large inductors | Magnetic bias in VFD systems |
5. Core Technological Innovations
1. 3D Magnetic Field Modeling
Spatial flux reconstruction (vs. legacy 2D planar monitoring)
Precision: ±3% vector angle error (validated per IEC 61000-4-8)
2. Edge-Cloud Hybrid Architecture
Layer | Function | Benefit |
| Edge | Real-time feature extraction | <5ms latency for critical alerts |
| Cloud | AI-driven predictive analytics | 90%+ model accuracy |
3. Non-Invasive Deployment
Live-grid installation: Zero downtime (compatible with 110kV~1000kV)
Universal adapter kits: Fit 97% of global reactor form factors
Application of ITB & DKNC cooperation projects:
Case 1: UK ±525kV Shetland HVDC Link
Challenge: Traditional current-harmonic monitoring (IEEE C57.149) missed >40% of latent inter-turn shorts in smoothing reactors, risking €2.3M failure.
Solution: DKNC's 3D GMR sensors detected 2-turn faults via 0.3mT flux distortion analysis under 50mT EMI, triggering protection within 15ms.
Outcome: 100% fault detection (validated by DNV GL Class 1), 72-hour early warning, and zero forced outages over 18-month operation.
Case 2: Saudi NEOM 500kV Smart Substation
Challenge: Desert heat (55°C) accelerated reactor insulation decay, with manual inspections missing 35% defects.
Solution: Our edge-cloud hybrid system localized 46 hotspots via 3D thermal-magnetic coupling analytics, auto-generating SAP/EAM work orders.
Outcome: 62% OPEX reduction ($540k/year), 9-minute fault location (from 4 hours), and SEC-certified 3-day deployment vs. industry-standard 3 weeks.
