New IEEE Standard - Inactive-Reserved.
Guidance is provided for measuring the electric-field strength, ion-current density, conductivity, monopolar space-charge density, and net space-charge density in the vicinity of HVDC power lines, in converter substations, and in apparatus designed to simulate the HVDC power-line environment.

The purpose of this document is to provide guidance for the measurement of the electric-field strength, ion-current density, conductivity, monopolar space-charge density, and net space-charge density in the vicinity of high-voltage dc (HVDC) power lines, in converter substations, and in apparatus designed to simulate the HVDC power-line environment. The document
-Defines the terms that are used
-Describes the interrelationship between electrical parameters
- Describes operating principles of measuring instruments
- Suggests methods of calibration where applicable
- Describes measurement procedures
- Identifies significant sources of measurement error
