Research facility for the study of power system magnetic fields

摘要

A magnetic field research facility was constructed at EPRI's High Voltage Transmission Research Center (HVTRC) for the purpose of reproducing power system magnetic fields under controlled conditions. The facility includes a 1200' overhead distribution line that can be configured in different ways and a water distribution system that can be connected in different ways to the neutral wires. The distribution line serves a two-storey test residence and 18 other residences simulated by load cabinets. The electrical connections, grounding, electrical wiring and appliances of the test residences were designed to study the effect of source parameters on residential magnetic fields. Examples of measurements and applications of this facility are given.
