This standard applies to single- or multi-pole ac switches for rated voltage above 1000 V for use in switching shunt capacitor banks. This standard covers the application of capacitive load switching wherein the capacitive loads are separated by sufficient inductance to limit the transient peak inrush current to the peak values shown in Table 2 and Table 3. Switches designed and built in accordance with this standard are rated for routine switching of capacitive load currents only. This standard intends to be a comprehensive standard for all "specific duty" applications of switches in the area of switching shunt capacitor banks.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
C37.66-2021
IEEE Standard Requirements for Capacitor Switches for AC Systems (1 kV to 38 kV)
Required definitions, ratings, and procedures for performing design tests, production tests, and construction requirements for capacitor switches for ac systems from 1 kV to 38 kV are covered in this standard.
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No Superseded Standards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No Inactive-Withdrawn Standards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.
C37.66-2005
IEEE Standard Requirements for Capacitor Switches for AC Systems (1 kV to 38 kV)
Required definitions, ratings, and procedures for performing design tests, production tests, and construction requirements for capacitor switches for ac systems from 1kV to 38 kV are covered.
