The IEEE develops its standards through a consensus develop-ment process, approved by the American National S

Furthermore, the viewpoint expressed at thetime a standard is approved and issued is subject to change brought about through developments in t

When a document is more than five years old and has not been reaffirmed, it is reasonable to concludethat its contents, although s

33、 Foreword is not a part of IEEE Std 1227-1990, IEEE Guide for the Measurement of DC Electric-Field Strength andIon Related Quantities.)Because of interest in the electrical environment near high-voltage dc transmissions lines, the DC Fields andIons Working Group felt that there was a need to prepare
34、 a document that would provide some guidance forthe measurement of several relevant electrical parameters. The electrical parameters that are considered inthis standard include the electric-eld strength, the ion-current density, the monopolar charge density, andthe net space-charge density.The worki
35、ng group expresses its appreciation to Martin Misakian for his work in preparing the draft of thisdocument in collaboration with members of the working group. The text of the standard includes the resultsof many studies by researchers at the Bonneville Power Administration, the Electric Power Resear
36、ch Insti-tutes High-Voltage Transmission Research Center, Institut de Recherche dHydro-Qubec, the Jet Propul-sion Laboratory, and the National Institute of Standards and Technology. These studies were supported byinternal funding, as well as by funding from the U.S. Department of Energy and the Elec
37、tric Power ResearchInstitute. Constructive suggestions from those committees that had requested coordination have also beenincorporated into the text.At the time this standard was completed, the DC Field and Ions Working Group had the following membership:G.

Mobility is in the range of 10-9m to 10-7m2/Vs.NOTEHistorically, these have been referred to as large or Langevin ions. The use of the term charged aero
46、sols isencouraged.corona: A luminous discharge due to ionization of the air surrounding an electrode caused by a voltage gra-dient exceeding a certain critical value.current density: A vector-point function describing the magnitude and direction of charge flow per unit ar-ea. The preferred unit is a

48、td 1227-1990 IEEE GUIDE FOR THE MEASUREMENT OF DC ELECTRICNOTES:1 The convention in the discussion of electric elds near HVDC transmission lines has been to designate the electriceld into the ground as positive; i.e., the electric eld under a positive conductor is denoted as positive.2The time-invar
49、iant electric eld in this denition is an idealization of actual conditions. Typically, climatic effectswill perturb the space charge, which will then perturb the electric-eld strength.electric conductivity: The property of a material or medium permitting flow of electricity through its vol-ume, expressed as the ratio of the electric-current density to electric-field strength in a material or medium.For isotropic homogeneous media, the conductivity is a scalar quantity with the preferred unit, siemens permeter (S/m); 1 S/m = 1 mho/m.Faraday cage: A conduct
