Underground Conductor Electromagnetic Fields
Underground Conductor Electromagnetic Fields
The magnetic field exposure analysis tool is integrated with the underground cable systems (UGS) analysis module, and it determines the worst-case magnetic fields produced by conductors in underground raceways. The tool handles various 3-phase conductor layouts including flat and trefoil as well 1/C and 3/C 1-phase cables, dc cables, etc. The tool uses balanced & unbalanced load-flow currents and angles to determine the location and surface-level height of the worst-case magnetic field because of all conductors in the raceway.
Key Features
- Based on CIGRE JTF 36-0121
- Exposure to Surface Magnetic Fields from Underground Conductor Installations
- Evaluate Field Intensity Limits per IEEE C95.6-2002,
ICNIRP – 2010 & ACGIH – 2002 - Consider 3/C, 1/C, 3-P and 1-P AC & DC Conductor Currents
- Automatic filtering of Ferromagnetic Conduits
- User-Defined Permeability CF
- Validated against actual site measured magnetic fields
Capabilities
- Single-Plot / Multi-Plot / Plot Range
- Raceway Cable Location Depth View
- Graphical data visualization - Tooltip results, Scale breaks, Zoom in/out
- Export evaluation results to SQLite from any UGS Steady-State calculation
- Auto-filter selected conductor currents
- Consider Ferromagnetic Conduits
- Include Effect of Sheath Currents
Benefits
- Determine if your installation complies local magnetic field exposure limit regulations
- Identify magnetic field intensity for individuals with medical conditions
- Optimize cable layout and location to reduce magnetic field intensity problems
- Provide safer work environment and reduce long-term exposure to magnetic fields for workers and the public
