1 Scope This standard specifies the measurement method for total electric field strength and ion current density generated by DC converter station and transmission line. This standard is applicable to the measurement of total electric field strength and ion current density of converter station and DC transmission line (±800kV or below) under normal operation condition. 2 Normative References The following standards contain provisions which, through reference in this standard, constitute provisions of this standard. For dated references, subsequent amendments to (excluding correction to), or revisions of, any of these publications do not apply. However, the parties who enter into agreement according to this standard are encouraged to study whether the latest editions of these documents apply.
