IEC Phase-to-Phase Clearance Standards | PDF | Insulator (Electricity
Table 1 covers voltages from 1kV to 245kV and lists nominal system voltages, maximum equipment voltages, insulation levels, and minimum indoor and outdoor phase-to-earth and phase-to-phase
SUBSTATION ELECTRICAL BUS AND PARTS CLEARANCES
Considerable information has been published by CIGRE relative to establishing phase-to-phase air clearances in EHV substations as required by switching surges. The CIGRE method is based on
Bus Protection Theory
These requirements are necessary to keep the level of error voltage as low as possible to prevent maloperation of the relay. Making modifications to an existing bus protection scheme, such as adding
Non-segregated phase bus duct design guide
Non-segregated phase bus is an assembly of bus conductors with associated connections, joints and insulating supports confined within a metal enclosure without interphase barriers. The conductors are
