1.1 General

      This book is based on the tutorial and panel sessions presented by the subject matter experts (SME) of gas‐insulated substations in the working group K2 of the Institute of Electronics and Electrical Engineer (IEEE) Substations Committee. Gas‐insulated substations (GIS), for alternative current (AC) were invented in the early 1960s with the first projects in the mid‐1960s in the United States and Europe. In Japan, research and development for GIS started from 1963 followed by the practical application of 84 kV GIS (1968).

      With thousands of installed bays, of GIS today, we can look back to a wide range of experiences gained in very different cases of applications.

      The IEEE Substations Committee created the GIS Subcommittee K0 more than twenty‐five years ago and since then this subcommittee has continuously worked on standards and guides in the field of GIS technology and application. About twenty‐five standards and guides related to the GIS have been published to‐date, with continuous revision work in progress on all documents and preparation of new documents.

      Around the year 2000, the SME of the GIS Subcommittee started to collect information on GIS and developed a tutorial on Gas‐Insulated Substations (GIS) and Transmission Lines (GIL). This working group is numbered as K2 in the GIS Subcommittee and continually works to come up with new tutorials on different subjects associated with GIS.

      1.1.1 Organization

The organization of the Substations Committee was developed over the last decades with the focus being on any equipment and systems related to substations. In Table 1.1, the scope of the subcommittees of the substations committee is shown and in Figure 1.1, the organization of the Substations Committee is shown.

      IEEE PES Substations Committee has five subcommittees. Three subcommittees are for transmission and distribution (T&D) substations in physical electrical design (D0), physical civil design (E0), and grounding lightning (G0). One subcommittee for power electronic in T&D substations and one for gas‐insulated switchgear (GIS) (K0). For the scope of the subcommittees, see Table 1.1. The administrative substation committee (B0) is represented by the chair, vice‐chair, secretary, past‐chair and holds subcommittees for transactions editor, awards (H0), standards (S0), and meetings (M0).

Table 1.1 Scope of subcommittees of the substations committee

The standardization work is split into working groups of the five subcommittees which carry the responsibility for standards and guides. D0 for physical electrical design of substations has seven active working groups: Electrical Clearance D1 (IEEE 1427), Cable System in Substations D2 (IEEE 525), Bus Design D3 (IEEE 605), Seismic requirements to Substation Equipment D4 (IEEE 693), Flexible Bus works in Substations D5 (IEEE 1527), Turnkey Substations D8 (IEEE 1267), and AC/DC Power Supply Systems in Substations D9 (IEEE 1818).

      The physical civil design subcommittee E0 is active in six working groups on Community Acceptance of Substations E1 (IEEE 1127), Oil Spill prevention to the substation soil E2 (IEEE 980), Fire Protection E3 (IEEE 979), Animal Deterrents E5 (IEEE 1264), Measuring Earth Resistivity, Ground Impedance, Earth Surface Potentials of a Grounding System E6 (IEEE 81), and Electric Power Substation Physical and Electronic Security E7 (IEEE 1402).
