7、 so it willharmonize more closely with currently published IEC standards whenever possible. The standard has alsobeen updated to include many changes to provide for a more effective document that is now representativeof currently manufactured relay products used in the industry. The changes are as d
8、escribed in the followinglist. a) Clause 2, Normative references, has been added where required. b) Clause 3, Definitions, has been revised to provide for alphabetical classification by function. c) Clause 4, Service conditions, has been revised to provide categories for specific temperature rangesa
9、nd differentiation of ambient and extreme temperature ranges. Relative humidity now specifiesrelay or relay systems. Other conditions have been changed to show numeric designations. d) Clause 5, Electrical ratings, specifies additional standard current and voltage ratings and notes,applicable to Tab
10、le 3. Table 4 specifies additional maximum design voltages for dc control. Table 7and Table 8 specify coil resistance/burden at ambient temperature 25 C. A subclause has beenadded to address latching current requirements. e) Clause 6, Heating limits of temperature rise for coils, has been revised to
11、 add information on howthe temperature rise of the coils is to be determined. f) Clause 7, Mechanical requirements, has been added to provide information on the mechanicaldurability of relays, plug-in feature requirements, and relay setting controls to harmonize withcurrent IEC requirements. g) Clau
12、se 8, Insulation tests, was changed from Dielectric tests and now includes the requirement foran impulse voltage test as a design test. Table 9 and Figure 1 have been added to this clause. h) An annex of International Electrotechnical Commission (IEC) standards, relevant to IEEE Std C37.90,has been
13、added to provide additional information for clarification and harmonization with IECstandards. In preparing this standard, consideration has been given to the work of other committees,and especially to international standards that have been published or that are under preparation byTechnical Committ

IEEE Standard for Relays and Relay Systems Associated with Electric Power Apparatus 1. 1.1Overview This standard specifies standard service conditio
32、ns, standard ratings, performance requirements, and testing requirements for relays and relay systems used to protect and control power apparatus. The standard establishes a common reproducible basis for designing and evaluating relay and relay systems. Annex A provides a cross-reference to the appl
33、icable IEC standards. Certain specific tests required for relays and relay systems are covered in separate IEEE standards as noted below. Required surge tests are documented in IEEE Std C37.90.1-20021. Standardized test waveforms that are representative of surges observed and measured in actual inst
34、allations are applied to the terminals of the system. The relay or relay system must be able to withstand the applied surges without damage to components and without operating incorrectly. Required susceptibility tests are documented in IEEE Std C37.90.2-1995. The tests establish a method to evaluat
35、e the susceptibility of the relay under test to single frequency electromagnetic fields in the radio frequency domain, such as those generated by portable or mobile radio transceivers. Required electrostatic discharge tests are documented in IEEE Std C37.90.3-2001. Generators which that produce a st
36、andard waveform are used to apply discharges to conductive and non-conductive points on equipment under test. The test is performed to confirm that relays and relay systems will not misoperate or be damaged when installed, energized, and/or subjected to a specified electrostatic discharge. Scope Thi
37、s standard specifies standard service conditions, standard ratings, performance requirements, and testing requirements for relays and relay systems used to protect and control power apparatus. A relay system may include computer interface equipment and/or communications interface equipment, such as
38、a carrier transmitter/receiver or audio tone equipment. It does not cover relays designed primarily for industrial control, for switching communication or other low-level signals, or any other equipment not intended for control of power apparatus. 1Information about the documents referenced in this

IEEE Std C37.90-2005 IEEE Standard for Relays and Relay Systems Associated with Electric Power Apparatus 1.22. 3.a) b) c) d) e) f) 4.4.1Purpose The purpose of this standard is to establish a common reproducible basis for des
40、igning and evaluating relays and relay systems. Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any a
41、mendments or corrigenda) applies. IEEE Std C37.100, IEEE Standard Definitions for Power Switchgear.2,3Special terms A relay is an electric device designed to respond to input conditions in a prescribed manner and, after specified conditions are met, to cause contact operation or similar abrupt chang
42、e in associated electric control circuits. A relay may consist of several relay units, each responsive to a specified input, with the combination of units providing the desired overall performance characteristic of the relay. Inputs are usually electrical but may be mechanical, thermal, other quanti
43、ties, or a combination of quantities. Limit switches and similar simple devices are not relays. Relay terminology covers a wide area from the detailed relay structural principles through complex power system relay applications. The following basic areas of power system relay applications provide a c
