          This standard covers metal-enclosed switchgear assemblies incorporating gas insulating systems containing, but not limited to, such devices as interrupter switches; selector switches; fuses; circuit breakers; control, instrumentation and metering devices; and protective equipment. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for distribution of electrical power.<br />\n
          \t\t\t\t<br />\n
          This standard covers the design, testing, and installation of metal-enclosed switchgear that incorporates gas (typically SF6) at higher than ambient pressure as an insulation medium for alternating-current applications rated above 1 kV to 52 kV. The contents of the switchgear may include but are not limited to circuit breakers, switches, bushings, buses, instrument transformers, cable terminations, instrumentation, metering and controls, and protective relays. In a vertical section of the switchgear, some or all of the medium-voltage compartment(s) shall be composed of a gas pressure system for the primary insulating medium. This standard covers both indoor and outdoor installations.<br />\n
          This standard covers switchgear using sealed pressure systems or closed pressure systems. Switchgear employing controlled pressure systems is not covered by this standard.<br />\n
          This standard also does not cover switchgear that is covered under IEEE Std C37.20.2(TM), IEEE Std C37.20.3(TM), or IEEE Std C37.74(TM)-2014 that uses individual components that are gas-insulated such as switches, circuit breakers, and other equipment, nor does it fully cover those components that are covered by their individual component standards.

          Metal-enclosed switchgear assemblies incorporating gas insulating systems containing, but not limited to, such devices as interrupter switches; selector switches; fuses; circuit breakers; control, instrumentation, and metering devices; and protective equipment are covered in this standard.

          \t\t\t\t<br />\n
          This standard covers the design, testing, and installation of metal-enclosed switchgear that incorporates gas (typically SF6) at higher than ambient pressure as an insulation medium for alternating-current applications rated above 1 kV to 52 kV. The contents of the switchgear may include but are not limited to circuit breakers, switches, bushings, buses, instrument transformers, cable terminations, instrumentation, metering and controls, and protective relays. This standard applies if within a vertical section of the switchgear, some or all of the medium-voltage compartment(s) is composed of a gas pressure system for the primary insulating medium. This standard covers both indoor and outdoor installations. This standard covers switchgear using sealed pressure systems or closed pressure systems. Switchgear employing controlled pressure systems is not covered by this standard. This standard also does not cover switchgear that is covered under IEEE Std C37.20.2™, IEEE Std C37.20.3™, or IEEE Std C37.74™-2014 that uses individual components that are gas-insulated such as switches, circuit breakers, and other equipment, nor does it fully cover those components that are covered by their individual component standards.

          This standard covers the design, testing, and installation of metal-enclosed switchgear that incorporates gas (typically SF6) at higher than ambient pressure as an insulation medium for alternating-current applications rated above 1 kV to 52 kV. The contents of the switchgear may include but are not limited to circuit breakers, switches, bushings, buses, instrument transformers, cable terminations, instrumentation, metering and controls, and protective relays. In a vertical section of the switchgear, some or all of the medium-voltage compartment(s) shall be composed of a gas pressure system for the primary insulating medium.

          Revision Standard - Inactive-Reserved.<br />\n
          Standard methods and basic techniques for high-voltage testing applicable to all types of apparatus for alternating voltages, direct voltages, lightning impulse voltages, switching impulse voltages, and impulse currents are established in this standard. Sections that deal with alternating voltage, direct voltage, and impulse testing are combined in this revision to organize the technical content for ease of use. In addition, the concept of measurement uncertainty in evaluation of high-voltage and high-current tests is introduced in this version.<br />\n
          \t\t\t\t<br />\n
          This standard is applicable to - Dielectric tests with direct voltages - Dielectric tests with alternating voltages - Dielectric tests with impulse voltages - Tests with impulse currents - Tests with combinations of the above - Capacitance and dielectric loss measurements This standard is applicable only to tests on equipment with a rated voltage above 1000 V. Procedures are given for applying correction factors to convert test data to standard atmospheric conditions. This standard also specifies procedures for testing equipment when external insulation of the test object is to be subjected to dry, wet, or contaminated conditions.<br />\n
          The purpose of this standard is to<br />\n
          - Define terms of general applicability<br />\n
          - Present general requirements regarding test equipment and procedures<br />\n
          - Describe methods for evaluation of test results
