Superseded Standard

IEEE C37.90.1-1989

IEEE Standard Surge Withstand Capability (SWC) Tests for Protective Relays and Relay Systems

Superseded by IEEE C37.90.1-2002. Design tests intended for protective relays and relay systems, including those incorporating digital processors, are specified. The tests are intended to be applied to a complete relay system under simulated operating conditions. Oscillatory and fast transient test-wave shapes and characteristics are defined. The equipment to be tested and the test conditions are described, and the points of application of the test wave are shown. Acceptance is defined, and the requisite test data are specified.

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.


No Active Standards

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No Superseded Standards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No Inactive-Withdrawn Standards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
