Magnetic field reduction using high phase order lines

Ground level electric, and more recently magnetic, fields from overhead power transmission lines are increasingly important considerations in right-of-way specification, with states setting or planning to set edge-of-right-of-way limits.

Description
Summary:Ground level electric, and more recently magnetic, fields from overhead power transmission lines are increasingly important considerations in right-of-way specification, with states setting or planning to set edge-of-right-of-way limits. Research has been conducted on high-phase-order power transmission wherein six or twelve phases are used to transmit power in less physical space and with reduced electrical environmental effects compared with conventional designs. The first magnetic field testing verifies predictive methods for determination of magnetic fields from high-phase-order lines. Based on these analytical methods, field profiles are determined for lines of different phase order but comparable power capacity. Potential advantages of high phase order as a means of field mitigation are discussed.< >
