IEEE 1427-2020 - IEEE Approved Draft Guide for Recommended Electrical Clearances and Insulation Levels in Air Insulated Electrical Power Substations
This guide, covering three-phase ac systems 1 from 1 kV to 800 kV, provides recommended electrical operating and safety clearances and insulation levels in air-insulated electric supply substations; addresses insulation coordination procedures; provides design procedures for the selection and coordination of the insulation levels within the station as they relate to substation clearances; and addresses how reduced clearances in high-voltage ac substations may allow for compact bus arrangements and substation voltage uprating applications.
