24、introduction is not part of IEEE Std C37.90.1-2012, IEEE Standard for Surge Withstand Capability (SWC) Tests for Relays and Relay Systems Associated with Electric Power Apparatus. Assurance is needed that electronic relays and relay systems will operate satisfactorily when installed in the harsh env
25、ironment of a substation or switchyard. Standard surge tests will provide assurance that the relays and relay systems will withstand a specified surge level. The use of proper grounding and shielding techniques when installing the equipment will attenuate the actual surge level impinging on the equi
26、pment. However, even with proper grounding and shielding, surges may reach the equipment that are above the test levels specified in this standard. In such cases, the addition by the user of surge suppression devices external to the relay system may be required. The first standard document to specif
27、y an SWC Test was ANSI/IEEE Std C37.90a-1974/IEEE Std 472-1974 (redesignated ANSI/IEEE Std C37.90.1-1974), Guide for Surge Withstand Capability (SWC) Tests. Experience with ANSI/IEEE C37.90.1-1974 was good, and in 1978 the Guide was incorporated as Clause 9 of ANSI/IEEE Std C37.90-1978, IEEE Standar
28、d for Relays and Relay Systems Associated with Electric Power Apparatus. This meant that the oscillatory SWC Test became a required test for relays and relay systems containing semiconducting devices. From the beginning, it was realized that the oscillatory SWC test had limitations and did not adequ
29、ately represent all conducted transients that may be experienced in substation environments. The need for a complementary test was recognized and the general type of test required was identified. The problem then became one of a search for a circuit that would produce a repeatable, controllable outp
30、ut. During the search, the IEC showering arc test was studied as well as a number of other tests proposed by various organizations. These were not chosen because they were not repeatable or controllable. The combination of the original oscillatory SWC test and the fast transient SWC test ensure that
31、 relays and relay systems will function at a level of immunity in the presence of conducted transients that occur in substations. The fast transient test was therefore incorporated into ANSI/IEEE Std C37.90.1-1989, because it is stable, easy to control and can be performed in a minimum time and at a
32、 reasonable cost. A working group was later assembled to harmonize ANSI/IEEE Std C37.90.1-1989 with corresponding IEC standards and to make the standard more understandable through clarifications and improvements to the document. This working group made extensive revisions such that one set of tests
33、 are necessary to reach closer harmonization with the corresponding IEC standards. Copyright 2012 IEEE. All rights reserved. ix Contents 1. Overview 1 1.1 Scope . 1 1.2 Purpose 1 2.

39、: IEEE Standards documents are not intended to ensure safety, health, or environmental protection, or ensure against interference with or from other devices or networks. Implementers of IEEE Standards documents are responsible for determining and complying with all appropriate safety, security, envi
40、ronmental, health, and interference protection practices and all applicable laws and regulations. This IEEE document is made available for use subject to important notices and legal disclaimers. These notices and disclaimers appear in all publications containing this document and may be found under
41、the heading “Important Notice” or “Important Notices and Disclaimers Concerning IEEE Documents.” They can also be obtained on request from IEEE or viewed at http:/standards.ieee.org/IPR/disclaimers.html. 1. Overview 1.1 Scope This standard specifies design tests for relays and relay systems that rel
42、ate 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
43、met. The application of SWC tests to equipment other than relays and relay systems is the responsibility of those specifying the testing. 1.2 Purpose This standard establishes a common and reproducible basis for evaluating the performance of relays and relay systems when subjected to repetitive tran
44、sients on supply, signal, control, and communication lines or connections. This standard establishes that an evaluation is performed during both normal (non-tripped) and abnormal (tripped) relay operating conditions.
