Electric and Magnetic Field Quantification of Commercial, Industrial and Transportation Technologies

Electric Research staff includes several engineers with career length experience designing and conducting measurement programs to quantify the electrical characteristics of power delivery systems. Electric Research staff members have experience in related areas such as advanced data acquisition, data analysis techniques, and the development of computer-aided techniques for economically reducing and reporting comprehensive data. This background has enabled Electric Research to offer imaginative and effective field measurement services to utility, industrial, commercial, and governmental clients. Examples of completed studies are:

• Waveform data collected in 28 homes in Pennsylvania, Florida, Connecticut, and California. Samples of magnetic fields and currents were recorded every minute over 24 hour periods.

   

• Waveform and dc magnetic field data collected in substations, industrial complexes, laboratories, MRI, and commercial office facilities.

   

• Waveform and dc magnetic field data to quantify and characterize the magnetic and electric field environment within and in the vicinity of the Transrapid TR07 Maglev vehicle operating on the Emsland FRG Transrapid Test Facility. More comprehensive measurements (including electric fields and transient magnetic fields) were measured and reported for the AMTRAK electrified trains, the Boston Metro System, the Washington, DC Metro System, and the French TGV-A System.

   

• Waveform, dc, and transient magnetic field data were recorded in two prototype electric vehicles. These measurements were conducted with each vehicle on a dynamometer for standard industry and federal test cycles. Magnetic field measurements were also performed on the vehicle battery chargers for a variety of charge conditions.

   

• Waveform data in the ELF band and both VLF and LF band rms data to quantify the magnetic fields in the three dimensional space around appliances. These measurements show the magnetic field attenuation up to 3 meters (10 feet) from the appliance surface.

   

• RMS spot measurements in ten different elementary schools. These measurements consisted of magnetic field profiles and source identification.

   

• Numerous RMS magnetic field profiles from operating transmission lines, distribution lines, and in personal residences. Data for source identification is available.
