Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
PC37.122a
Standard for High-Voltage Gas-Insulated Substations Rated Above 52 kV–Amendment: Voltage Levels for Disconnect Switch Open Gap, Power-Frequency Withstand Testing
This amendment clarifies the required test voltage level for disconnect switch open gap, power-frequency withstand testing. The clarification states that the values shown in the 3rd column of Table 1 are only required for type testing and values of the 2nd column of Table 1 define the requirement for routine testing.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
C37.122-2021
IEEE Standard for High-Voltage Gas-Insulated Substations Rated Above 52 kV
The technical requirements for the design, fabrication, testing, and installation of a gas insulated substations are covered. The parameters to be supplied by the purchaser are set, and the technical requirements for the design, fabrication, testing, and installation details to be furnished by the manufacturer are established.
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No Superseded Standards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No Inactive-Withdrawn Standards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.
C37.122-2010
IEEE Standard for High Voltage Gas-Insulated Substations Rated Above 52 kV
The technical requirements for the design, fabrication, testing, and installation of a gasinsulated substations are covered. The parameters to be supplied by the purchaser are set, and the technical requirements for the design, fabrication, testing, and installation details to be furnished by the manufacturer are established.
