The terms and definitions in the standard are intended to encompass the products within the scope of the IEEE C37 list of power switchgear standards for high-voltage circuit breakers (above 1000 Vac and 3200 Vdc) and for reclosers and other distribution equipment (above 1000 Vac to 38,000 Vac) as used primarily in connection with generation, transmission, distribution, and conversion of electric power. For terms not defined within this standard, the definitions within IEEE Std C37.20.10 apply.

This standard presents basic requirements for the design, testing and application of microprocessor-based controls of distribution switchgear rated above 1 kV up to and including 38 kV. The standard is intended to mitigate the effects of the harsh environments which may be encountered outside the protections provided by a typical substation. This standard applies to microprocessor-based devices employed in distribution switchgear typically mounted on power poles, in wet or dry vaults, or in pad… read more mounted switchgear enclosures. This standard also does not apply to microprocessor-based devices employed in high voltage circuit breakers (IEEE C37.04 "Standard Rating Structure for AC High-Voltage Circuit Breakers") or metal-enclosed switchgear (IEEE C37.20.2 "Standard Metal-Clad Switchgear" and IEEE C37.20.3 "Standard for Metal-Enclosed Interrupter Switchgear"). This standard does not invalidate any tests performed on power system protective relays which are designed to IEEE C37.90 ("Standard for Relays and Relay Systems Associated with Electric Power Apparatus"). Lastly, this standard will not cover the design of the control enclosure such as mounting, latching, or user accessibility. read less

This standard does not apply to microprocessor-based devices employed in high voltage circuit breakers (IEEE Std C37.04™, Standard for Ratings and Requirements for AC High-Voltage Circuit Breakers with Rated Maximum Voltage Above 1000 V) or metal-enclosed switchgear [IEEE Std C37.20.2™, Standard for Metal-Clad Switchgear and IEEE Std C37.20.3™, Standard for Metal-Enclosed Interrupter Switchgear (1 kV- 38 kV)]. This standard does not invalidate any tests performed on power system protective relays which are designed to IEEE Std C37.90™, Standard for Relays and Relay Systems Associated with Electric Power Apparatus. Lastly, this standard does not cover the design of the control enclosure such as mounting, latching, or user accessibility, and does not supersede the requirements of controls which are defined and tested per the switchgear equipment standard. read less
