          The testing procedures for all high-voltage circuit breakers that include all voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the preferred ratings as listed in ANSI C37.06-1997 are covered. Typical circuit breakers covered by these standards have maximum voltage ratings from 4.76 kV through 800 kV, and continuous current ratings of 600 A, 1200 A, 2000 A, and 3000 A associated with the various maximum voltage ratings. The test procedures verify all assigned ratings, including continuous current, dielectric withstand voltages, short-circuit current, transient recovery voltage, and capacitor switching, plus associated capabilities such as mechanical endurance, load current, and out-of-phase switching. Production test procedures are also included. This standard does not cover generator circuit breakers as these are covered in IEEE Std C37.013-1993.<br />\n
          \t\t\t\t<br />\n
          This test procedure summarizes the various tests that are made on ac high-voltage indoor and outdoor circuit breakers, except for generator circuit breakers, which are covered in IEEE Std C37.013-1997. It describes accepted methods used in making the tests and specifies the tests that will verify assigned ratings under ANSI/IEEE standards. This procedure does not preclude the use of other equivalent or more effective methods of demonstrating ratings.<br />\n
          The tests are divided into the following classifications:<br />\n
          a) Design tests (Referred to in IEC 60056-1987 and IEC 60694-1996 as Type Tests)<br />\n

          The testing procedures for all high-voltage circuit breakers that include all voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the preferred ratings as listed in ANSI C37.06-1997 are covered. Typical circuit breakers covered by these standards have maximum voltage ratings from 4.76 kV through 800 kV, and continuous current ratings of 600 A, 1200 A, 2000 A, and 3000 A associated with the various maximum voltage ratings. The test procedures verify all assigned ratings, including continuous current, dielectric withstand voltages, short-circuit current, transient recovery voltage, and capacitor switching, plus associated capabilities such as mechanical endurance, load current, and out-of-phase switching. Production test procedures are also included. This standard does not cover generator circuit breakers as these are covered in IEEE Std C37.013-1993.<br />\n
          \t\t\t\t<br />\n
          This test procedure summarizes the various tests that are made on ac high-voltage indoor and outdoor circuit breakers, except for generator circuit breakers, which are covered in IEEE Std C37.013-1997. It describes accepted methods used in making the tests and specifies the tests that will verify assigned ratings under ANSI/IEEE standards. This procedure does not preclude the use of other equivalent or more effective methods of demonstrating ratings.<br />\n
          The tests are divided into the following classifications:<br />\n
          a) Design tests (Referred to in IEC 60056-1987 and IEC 60694-1996 as Type Tests)<br />\n

          New IEEE Standard - Superseded.<br />\n
          The various tests that are made on AC high-voltage circuit breakers are summarized. Accepted methods used in making the tests are described, and the tests that will demonstrate ratings under ANSI/IEEE standards are specified. The following categories of tests are considered: design tests, production tests, tests after delivery, field tests, and conformance tests.<br />\n
          \t\t\t\t<br />\n
          This test procedure summarizes the various tests which are made on ac high-voltage circuit breakers, describes accepted methods used in making the tests, and specifies the tests which will demonstrate ratings under ANSI/IEEE standards. It does not preclude the use of other equivalent or more effective methods of demonstrating ratings.<br />\n
          The tests are divided into the following classifications<br />\n
          --Design tests<br />\n
          --Production tests<br />\n
          --Tests after delivery<br />\n
          --Field tests<br />\n
          --Conformance tests<br />\n
          The purposes of the test procedure are:1) To establish that a circuit breaker of the design on test can perform satisfactorily, both electrically and mechanically, up to the ratings assigned to it; 2) To establish that production breakers have been adequately tested during manufacture and after assembly and that the breakers have characteristics essentially the same as the breaker of identical design which was subjected to design tests

          The testing procedures for all high-voltage circuit breakers that include voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the preferred ratings as listed in IEEE Std C37.04™ are covered. Typical circuit breakers covered by these standards have maximum voltage ratings from 4.76 kV through 800 kV, and continuous current ratings of 600 A through 5000 A associated with the various maximum voltage ratings. The test procedures verify all assigned ratings, including continuous current, dielectric withstand voltages, short-circuit current, transient recovery voltage, and capacitor switching, plus associated capabilities such as mechanical endurance, load current, and out-of-phase switching. Production test procedures are also included. This standard does not cover generator circuit breakers as these are covered in IEC/IEEE 62271-37-013.<br />\n

          This standard applies to alternating current (ac) high-voltage circuit breakers with rated maximum voltage above 1000 V. It defines various tests that are made on ac high-voltage circuit breakers, except for generator circuit breakers, which are covered in IEC/IEEE 62271-37-013:2015. It specifies the tests and describes the accepted methods used to verify assigned ratings defined in IEEE Std C37.04. It also describes the test procedures associated with production and field installation. The test procedures are divided into the following classifications: a) Design tests; b) Production tests; c) Conformance tests; d) Field tests. NOTE--Design tests are referred to as &quot;Type&quot; tests, and Production tests are referred to as &quot;Routine&quot; tests in IEC standards.

          The testing procedures for all high-voltage circuit breakers that include voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the preferred ratings as listed in IEEE Std C37.04(TM) are covered. Typical circuit breakers covered by these standards have maximum voltage ratings from 4.76 kV through 800 kV, and continuous current ratings of 600 A through 5000 A associated with the various maximum voltage ratings. The test procedures verify all assigned ratings, including continuous current, dielectric withstand voltages, short-circuit current, transient recovery voltage, and capacitor switching, plus associated capabilities such as mechanical endurance, load current, and out-of-phase switching. Production test procedures are also included. This standard does not cover generator circuit breakers as these are covered in IEC/IEEE 62271-37-013. (Note: IEEE Std C37.09-2018 requires the use of a color monitor (and color printer) to view many of the graphics contained in this standard. Color is essential to the understanding of the graphics.)<br />\n

          This standard applies to ac high-voltage circuit breakers with rated maximum voltage above 1000 V. It defines various tests that are made on ac high-voltage circuit breakers, except for generator circuit breakers, which are covered in IEC/IEEE 62271-37-013:2015 (formerly IEEE Std C37.013(TM)-1997). It specifies the tests and describes the accepted methods used to verify assigned ratings defined in IEEE Std C37.04(TM).4 It also describes the test procedures associated with production and field installation. The test procedures are divided into the following classifications: a) Design tests; b) Production tests; c) Conformance tests; d) Field tests. NOTE--Design tests are referred to as “Type” tests, and Production tests are referred to as “Routine” tests in IEC standards.

          The testing procedures for all high-voltage circuit breakers that include voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the preferred ratings as listed in IEEE Std C37.04(TM) are covered. Typical circuit breakers covered by these standards have maximum voltage ratings from 4.76 kV through 800 kV, and continuous current ratings of 600 A through 5000 A associated with the various maximum voltage ratings. The test procedures verify all assigned ratings, including continuous current, dielectric withstand voltages, short-circuit current, transient recovery voltage, and capacitor switching, plus associated capabilities such as mechanical endurance, load current, and out-of-phase switching. Production test procedures are also included. This standard does not cover generator circuit breakers as these are covered in IEC/IEEE 62271-37-013. (Note: IEEE Std C37.09-2018 requires the use of a color monitor (and color printer) to view many of the graphics contained in this standard. Color is essential to the understanding of the graphics.)<br />\n

          This standard applies to ac high-voltage circuit breakers with rated maximum voltage above 1000 V. It defines various tests that are made on ac high-voltage circuit breakers, except for generator circuit breakers, which are covered in IEC/IEEE 62271-37-013:2015 (formerly IEEE Std C37.013(TM)-1997). It specifies the tests and describes the accepted methods used to verify assigned ratings defined in IEEE Std C37.04(TM).4 It also describes the test procedures associated with production and field installation. The test procedures are divided into the following classifications: a) Design tests; b) Production tests; c) Conformance tests; d) Field tests. NOTE--Design tests are referred to as “Type” tests, and Production tests are referred to as “Routine” tests in IEC standards.

          Amendment Standard - Superseded.<br />\n
          A revision to the capacitance current switching standards is included in this amendment.<br />\n
          \t\t\t\t<br />\n
          The scope of PC37.09a is to incorporate IEC 62271-100 capacitance current switching treatment into the circuit breaker test code. This applies to Circuit Breakers above 1000V ac.<br />\n
          Capacitance current switching was not addressed in C37.09-1999 to take advantage of a joint IEC/IEEE working group on this subject. This Amendment will bring about harmonization with the new IEC 62271-100.

          The testing procedures for all high-voltage circuit breakers that include all voltage ratings above 1000 V ac and comprise both indoor and outdoor types having the preferred ratings as listed in ANSI C37.06-1997 are covered. Typical circuit breakers covered by these standards have maximum voltage ratings from 4.76 kV through 800 kV, and continuous current ratings of 600 A, 1200 A, 2000 A, and 3000 A associated with the various maximum voltage ratings. The test procedures verify all assigned ratings, including continuous current, dielectric withstand voltages, short-circuit current, transient recovery voltage, and capacitor switching, plus associated capabilities such as mechanical endurance, load current, and out-of-phase switching. Production test procedures are also included. This standard does not cover generator circuit breakers as these are covered in IEEE Std C37.013-1993.<br />\n

          This test procedure summarizes the various tests that are made on ac high-voltage indoor and outdoor circuit breakers, except for generator circuit breakers, which are covered in IEEE Std C37.013-1997. It describes accepted methods used in making the tests and specifies the tests that will verify assigned ratings under ANSI/IEEE standards. This procedure does not preclude the use of other equivalent or more effective methods of demonstrating ratings.<br />\n

          New IEEE Standard - Superseded.<br />\n
          The various tests that are made on AC high-voltage circuit breakers are summarized. Accepted methods used in making the tests are described, and the tests that will demonstrate ratings under ANSI/IEEE standards are specified. The following categories of tests are considered: design tests, production tests, tests after delivery, field tests, and conformance tests.<br />\n
          \t\t\t\t<br />\n
          This test procedure summarizes the various tests which are made on ac high-voltage circuit breakers, describes accepted methods used in making the tests, and specifies the tests which will demonstrate ratings under ANSI/IEEE standards. It does not preclude the use of other equivalent or more effective methods of demonstrating ratings.<br />\n
          The tests are divided into the following classifications<br />\n
          --Design tests<br />\n
          --Production tests<br />\n
          --Tests after delivery<br />\n
          --Field tests<br />\n
          --Conformance tests<br />\n
          The purposes of the test procedure are:1) To establish that a circuit breaker of the design on test can perform satisfactorily, both electrically and mechanically, up to the ratings assigned to it; 2) To establish that production breakers have been adequately tested during manufacture and after assembly and that the breakers have characteristics essentially the same as the breaker of identical design which was subjected to design tests

          New IEEE Standard - Superseded.<br />\n
          This standard is a revision of ANSI C37.06-1997. It reflects small editorial changes needed to coordinate with the final wording contained in the defining standards ANSI/IEEE C37.04-1999 and ANSI/IEEE C37.09-1999. Some ratings have also been updated. Because this revision is primarily editorial in nature, this Foreword describes the substantive and editorial changes between this revision and the 1987 version.<br />\n
          The format of the tables remains very much the same, except that some ratings, which had been given in the notes (sometimes on a different page from the table of preferred ratings), have been listed explicitly in the tables.<br />\n
          \t\t\t\t<br />\n
          This standard is applicable to three-pole circuit breakers used in three-phase systems and single-pole circuit breakers used in single-phase systems, both indoor and outdoor AC high-voltage types, rated above 1000 volts on a symmetrical current basis. This standard does not cover circuit breakers used at rated frequencies other than 50 Hz or 60 Hz, or generator circuit breakers that are covered in IEEE Std. C37.013.<br />\n
          Since the existing rating structures are being revised under related projects PC37.04a, PC37.04b, PC37.09a, PC37.09b, PC37.011 and PC37.012, the purpose of this work is to provide relevant values of preferred ratings for the new rating structures. Another purpose is to integrate C37.06, formerly sponsored by NEMA, into the IEEE SA process of standards dvelopment. Sponsorship is now being transferred to the IEEE Switchgear Committee.

          New IEEE Standard - Superseded.<br />\n
          This standard is a revision of ANSI C37.06-1997. It reflects small editorial changes needed to coordinate with the final wording contained in the defining standards ANSI/IEEE C37.04-1999 and ANSI/IEEE C37.09-1999. Some ratings have also been updated. Because this revision is primarily editorial in nature, this Foreword describes the substantive and editorial changes between this revision and the 1987 version.<br />\n
          The format of the tables remains very much the same, except that some ratings, which had been given in the notes (sometimes on a different page from the table of preferred ratings), have been listed explicitly in the tables.<br />\n
          \t\t\t\t<br />\n
          This standard is applicable to three-pole circuit breakers used in three-phase systems and single-pole circuit breakers used in single-phase systems, both indoor and outdoor AC high-voltage types, rated above 1000 volts on a symmetrical current basis. This standard does not cover circuit breakers used at rated frequencies other than 50 Hz or 60 Hz, or generator circuit breakers that are covered in IEEE Std. C37.013.<br />\n
          Since the existing rating structures are being revised under related projects PC37.04a, PC37.04b, PC37.09a, PC37.09b, PC37.011 and PC37.012, the purpose of this work is to provide relevant values of preferred ratings for the new rating structures. Another purpose is to integrate C37.06, formerly sponsored by NEMA, into the IEEE SA process of standards dvelopment. Sponsorship is now being transferred to the IEEE Switchgear Committee.
