Title
Standard for Insulation Coordination - Definitions, Principles, and Rules

The Institute of Electrical and Electronics Engineers, Inc.

Publication Date:
Jul 18, 1996

Scope:

This standard applies to three-phase ac systems above 1 kV. It specifies the procedure for selection of the withstand voltages for equipment phase-to-ground and phase-to-phase insulation systems. It also identifies a list of standard insulation levels, based on the voltage stress to which the equipment is being exposed.

Keywords:

protective margin

protective ratio

insulation coordination

standard withstand voltages

phase-to-ground insulation configuration

ground fault factor

basic lightning impulse insulation level (BIL)

basic switching impulse insulation level (BSL)

voltage stress

crest value

atmospheric correction factor

phase-to-phase insulation configuration

overvoltage
