19、ciples, and Rules.) This standard is a revision of IEEE Std 1313-1993. This standard presents the defi nitions and the procedure for insulation coordination. A related draft standard, IEEE P1313.2, is an application guide, which presents practical examples. A new concept in this standard is the addi
20、tion of phase-to-phase insulation coordination, and longitudinal insulation coordination, which is the coordination of switching surges and power frequency voltage across an open switch. The introduction of the very fast front short-duration overvoltages is an acknowledgment of the problems observed
21、 when a disconnect switch operates in a gas-insulated substation (GIS). The basic concept of insulation coordination remains the same as in IEEE Std 1313-1993. The fi rst step is the determination of voltage stresses using digital computer simulation, a transient analyzer, or mathematical methods. T
22、hese analyses result in nonstandard overvoltage waveforms, which have to be converted to an equivalent standard waveshape. The second step is the selection of insulation strength to achieve the desired level of probability of failure. The standard considers both the BIL and BSL as either a conventio
23、nal or sta- tistical variable. For equipment in Class I (1240 kV), use of the low-frequency withstand voltage and light- ning impulse withstand voltage are recommended. For Class II ( 242 kV), use of the lightning impulse withstand voltage and switching withstand voltage are recommended. This standa
24、rd was prepared by the Insulation Coordination Working Group, under the sponsorship of the Technical Council of the IEEE Power Engineering Society. At the time this standard was completed, the Insulation Coordination Working Group had the following membership: George G. Karady, Chair The following p

33、1 IEEE Standard for Insulation Coordination Defi nitions, Principles, and Rules 1. Overview 1.1 Scope This standard applies to three-phase ac systems above l kV. It specifi es the procedure for selection of the withstand voltages for equipment phase-to-ground and phase-to-phase insulation systems. I
34、t also identifi es a list of standard insulation levels, based on the voltage stress to which the equipment is being exposed. 1.2 Purpose The purpose of this standard is to a) Defi ne applicable terms b)Outline insulation coordination procedures c)Identify standard insulation levels 1.3 Applications
35、 The insulation coordination procedure described in this standard is generally applicable to all type of appara- tus. However, alternative insulation levels and test voltages may be required or permitted by the appropriate apparatus standards. The insulation coordination of rotating machines is not
36、considered in this standard, but the basic concepts may be applicable. Insulation levels (transmission line) may be different from those identifi ed as standard insulation levels but the methods of insulation coordination are applicable.
