Full Description

Scope

This document provides a recommended practice for the arrangement principle of measurement points, the method of measurement, the analysis of measurement data, and the evaluation of measurement results for the corridor of overhead power transmission lines in parallel mixed with alternating current (ac) and direct current (dc), which can provide guidance for monitoring electromagnetic environmental of power transmission lines, as well as engineering design and equipment selection. This document is applicable to measure the electromagnetic environment of the joint region under the ac and dc parallel transmission lines, whose maximum distance shall not exceed 100 m, the voltage shall not be less than 100 kV for ac transmission line and A?400 kV for dc transmission line.

Abstract

New IEEE Standard - Active.Uniform procedures for the measurement of the power frequency electric field and dc electric field when ac/dc power transmission lines are installed in parallel or on shared towers are established in this recommended practice. Based on the mutual influence analysis between parallel ac/dc power transmission lines through the theoretical calculation and on-site measurements, the specification requirements and calibration methods of electric field meters are specified. The measurement ranges and layout of measurement points, data recording and processing, and result evaluation methods of parallel power transmission lines of different voltage levels are standardized. This recommended practice is applicable to electromagnetic environment measurement of ac transmission lines with a voltage not less than 100 kV, dc transmission lines with a voltage not less than A? 400 kV, and parallel transmission lines with a distance not over 100 m.
