Title
Surge Withstand Capability (SWC) Tests for Relays and Relay Systems Associated with Electric Power Apparatus
The Institute of Electrical and Electronics Engineers, Inc.
Publication Date:
Aug 20, 2003
Scope:
This standard specifies design tests for relays and relay systems that relate to the immunity of this equipment to repetitive electrical transients. Two types of tests are specified. The oscillatory and fast transient SWC tests are defined as distinct tests. However, it is not intended to prohibit a combined test, provided all requirements of the individual SWC tests are met.
The application of SWC tests to equipment other than relays and relay systems is the responsibility of those specifying the testing.
Keywords:
- relay systems
- fast transient test
- relay
- oscillatory test
- surge withstand capability
