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.
