Engineering literature

Three engineering handbooks under the title “Magnetic Field Management for Overhead Transmission Lines” are available. These handbooks provide information on common magnetic field management applications. The first handbook, “A Primer,” brings together much of the materials on transmission line magnetic fields developed over the past decade. The handbook provides an overview of magnetic field fundamentals and characterizes fields from overhead transmission lines, covering such topics as spatial uniformity, temporal stability, harmonic content and field orientation in space. The second handbook, “Potential Options for Low-Field Designs,” recommends several options for reducing transmission line magnetic fields. Tutorial material explains how transmission line design determines magnetic field levels and the typical levels associated with various line designs are. The third handbook, “Field Reduction Using Cancellation Loops,” explains the principles of cancellation loop operation and provides the utility engineer with tools to design and construct such systems.
