New IEEE Standard - Active.
Basic requirements intended to mitigate the effects of the harsh environments encountered by microprocessor-based controls of distribution switchgear rated above 1 kV up to and including 38 kV are covered. Basic requirements include the design, testing and application of microprocessor-based controls. Microprocessor-based controls covered by IEEE Std C37.68™ are intended to be applied in distribution switchgear which is normally mounted on power poles, in wet or dry vaults, or in pad-mounted switchgear enclosures.

This standard presents basic requirements for the design, testing, and application of microprocessor-based controls of distribution switchgear rated above 1 kV and up to and including 38 kV. The standard is intended to mitigate the effects of the harsh environments that 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-mounted switchgear enclosures. 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.
Distribution switchgear is typically mounted on power poles, in wet or dry vaults, or in pad-mounted enclosures and is used with overhead or underground electric utility distribution lines. The evolution of distribution device controls from hydraulic and the electro-mechanical to microprocessor-based has also led to the controls being mounted on power poles, in pad-mounted switchgear, and in vaults. These locations expose the microprocessor-based controls to the harsh environmental, mechanical, and electrical conditions of the electric utility distribution lines
