18、s not a part of IEEE Std 1313.2-1999, IEEE Guide for the Application of Insulation Coordination.)This guide is the second part of a major revision of ANSI C92.1-1982. The guide is divided into two parts:IEEE Std 1313.1-1996 (Part 1) presents the definitions and the procedure for insulation coordinat

19、ion. IEEEStd 1313.2-1999 (Part 2) is an application guide, which presents practical examples. The technical content ofPart 2, particularly 6.2 and 6.3, is taken with permission from the book Insulation Coordination for PowerSystemby Andrew R. Hileman, published by Marcel Dekker Inc., New York, NY. N

20、ew additions to this guide include the concepts of phase-phase insulation coordination and longitudinalinsulation coordination, which considers switching surges and the power frequency voltage across an openswitch. The introduction of the very fast front short-duration overvoltages is an acknowledgm

21、ent of theproblems observed when a disconnect switch operates in a gas insulated substation (GIS).The basic concept of insulation coordination remains the same as in ANSI C92.1-1982. The first step is thedetermination of voltage stresses using digital computer simulation, transient analyzer, or math

22、ematicalmethods such as those presented in this guide. These analyses result in nonstandard overvoltage waveforms,which are converted to equivalent standard wave shapes. The second step is the selection of insulationstrength to achieve the desired level of probability of failure. The standard descri

23、bes the determination ofboth the conventional and statistical BIL and BSL.This standard is prepared by the Insulation Coordination Working Group, under the sponsorship of the Tech-nical Council of the IEEE Power Engineering Society.

Overview1.1 ScopeThe insulation coordination standard and guide apply to three-phase ac systems above 1 kV and are dividedinto two parts.IEEE Std 1313.1-1996 (Part 1) specif

33、ies the procedure for selection of the withstand voltages basic light-ning impulse insulation level (BIL) and basic switching impulse insulation level (BSL) for equipmentphase-ground and phase-phase insulation systems. It also identifies a list of standard insulation levels.Although the principles o

34、f this standard also apply to transmission line insulation systems, the insulationlevels may be different from those identified as standard insulation levels.This guide (Part 2) is an application guide with practical examples, intended to provide guidance in the deter-mination of the withstand volta

35、ges and to suggest calculation methods and procedures. The insulation coor-dination examples for selected equipment are designed to explain the principles of Part 1. The guide isintended for air-insulated ac systems; caution should be exercised in the case of gas-insulated systems (GIS).1.2 PurposeI

36、t should be recognized that absolute protection of station equipment is theoretically impossible. Even ifarresters are located at the terminals of all apparatuses, equipment failures can occur. The probabilisticmethod, that is, designing for a mean time between failures (MTBF) criterion, is proposed

37、 here not only topermit a realistic basis of design, but perhaps more importantly, to form a consistent measure of designbased on reliability.2.
