This guide presents methods for online monitoring and recording of the transient overvoltages in a three-phase alternating current (AC) power system when the voltage level is higher than 1 kV. It applies to the qualitative measurement of transient overvoltages in substations, power stations, and transmission lines. The results are used for power system operating condition analyses. This guide does not include online monitoring and recording of very fast transient overvoltage (VFTO) caused by operation of gas-insulated switchgear (GIS) disconnectors.

IEEE Guide for Online Monitoring and Recording Systems for Transient Overvoltages in Electric Power Systems
The guide for the online monitoring and recording system of transient overvoltages in power system is used to regularize its methods, define the concrete structure of recording system for transient overvoltages, and identify the requirements of capability checkout and uncertainty in online monitoring and recording systems.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
