The following is the March 2006 list of SPDC NesCom approved (active) PARs in numerical order, showing the PAR number, Working Group responsible, URL for the complete PAR, Document Title and Scope.

PAR Number: PC62.21-2003/Cor 1 (PE/SPD/HV)
Working Group: WG 3.4.9 Surge Protection of Rotating Machinery
URL:
http://standards.ieee.org/board/nes/projects/C62-21-2003_Cor-1.pdf
Title: IEEE Guide for the Application of Surge Voltage Protective Equipment on AC Rotating Machinery 1000 Volts and Greater - Corrigendum 1: Correction to Equation A.3
Scope: Remove the square root radical from Equation A.3 in Annex A and correct three numbers in the associated illustrative example.

PAR Number: PC62.21.1 (PE/SPD/HV)
Working Group: WG 3.4.9 Surge Protection of Rotating Machinery
URL:
http://standards.ieee.org/board/nes/projects/C62-21-1.pdf
Title: Recommended Practice for the Application of Surge Voltage Protective Equipment on AC Rotating Machinery Rated 1000 V or Greater and Less than 30 kV, Generators and Single-Turn Coil Motors
Scope: This recommended practice covers the application of surge voltage protective equipment to ac rotating machinery rated 1 kV to 30 kV. This recommended practice covers rotating generators with and without generator circuit breakers, and single-turn coil motors. This recommended practice extends the surge protection guidance provided for form-wound multi-turn coil motors in IEEE C62.21-2003 to cover here the insulation surge voltage withstand strength, the surge environment and the application of surge voltage protection to motors and generators with windings having single-turn coils, and the surge environment and application of surge voltage protection to generators with windings having form-wound multi-turn coils.

PAR Number: PC62.22 (PE/SPD)
Working Group: Continuous Revision of C62.22
URL:
http://standards.ieee.org/board/nes/projects/C62-22.pdf
Title: IEEE Guide for the Application of Metal-Oxide Surge Arresters for Alternating-Current Systems
Scope: The scope of the IEEE Guide for the Application of Metal-Oxide Surge Arresters for Alternating-Current Systems (C62.22) covers the application of metal oxide surge arresters to safeguard electric power equipment against the hazards of abnormally high voltage. The scope does not include application of low voltage surge protective devices below 1000 V ac, except when applied to protect the secondary of transformer.
Revision of C62.22 is proposed to implement new information to reflect evolving technology and industry practices, and to clarify, reorganize, and improve the presentation of the application guide. The scope of the revised standard will be the same as the current standard, including arresters applied to a transformer secondary below 1000 V ac for the purpose of protecting the transformer.

PAR Number: PC62.23 (PE/SPD/HV)
Working Group: WG 3.4.11 Surge Protection of Generating Plants
URL:
http://standards.ieee.org/board/nes/projects/C62-23.pdf
Title: Application Guide for Surge Protection of Electric Generating Plants
Scope: This guide covers surges entering an electric generating plant via transmission and distribution lines and methods to reduce them; methods of protecting indoor and outdoor equipment, controls and communication systems within the plant switchyard, the plant proper and ancillary facilities within the premises such as fuel, ash, water, cooling, weather and warning systems, against direct strokes, incoming and internally generated surges.

PAR Number: PC62.82.1 (PE/SPD)
Working Group: Preferred Voltages and Insulation Coordination Standards Maintenance
URL:
http://standards.ieee.org/board/nes/projects/C62-82-1.pdf
Title: Standard for Insulation Coordination - Definitions, Principles, and Rules
Scope: This insulation coordination standard and guide apply to three-phase ac systems above 1 kV and are divided into two parts. This standard, the first part, specifies the procedure for selection of withstand voltages [basic lightning impulse insulation level (BIL) and basic switching impulse insulation level (BSL)] 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. Although the principles of this standard also apply to transmission line insulation systems, the insulation levels may be different from those identified as standard insulation levels. The other part is an application guide with practical examples, intended to provide guidance in the determination of the withstand voltages and to suggest calculation methods and procedures.

PAR Number: PC62.82.2 (PE/SPD)
Working Group: Preferred Voltages and Insulation Coordination Standards Maintenance
URL:
http://standards.ieee.org/board/nes/projects/C62-82-2.pdf
Title: Guide for the Application of Insulation Coordination
Scope: The insulation coordination standard and guide apply to three-phase as systems above 1 kV and are divided into two parts. This guide, the second part, is an application guide with practical examples, intended to provide guidance in the determination of the withstand voltages and to suggest calculation methods and procedures. The insulation coordination examples for selected equipment are designed to explain the principles of Part 1. The guide is intended for air-insulated as systems; caution should be exercised in the case of gas-insulated systems (GIS) This revision of the guide will address comments received during the recent document reaffirmation, will also address items contained in an IEC document on the same subject and will address any new information that is found.

PAR Number: PC62.92.3 (PE/SPD/HV)
Working Group: WG 3.5.7 Taskforce 3
URL:
http://standards.ieee.org/board/nes/projects/C62-92-3.pdf
Title: Guide for the Application of Neutral Grounding in Electrical Utility Systems, Part III—Generator Auxiliary Systems
Scope: The scope of this project is to summarize the general considerations in grounding of generating station auxiliary power systems, the factors to be considered in selecting between the appropriate grounding classes and specifying equipment ratings. This guide applies to both medium-voltage (1 kV-15 kV) and low-voltage (less than 1 kV) auxiliary power systems. The intent of this guide is to discuss grounding methods which may be used to limit equipment damage. The emphasis is on reliability and availability of auxiliary power system service, achieved through control of ground-fault currents and transient overvoltages.

PAR Number: PC62.92.4 (PE/SPD)
Working Group: Neutral Grounding Working Group
URL:
http://standards.ieee.org/board/nes/projects/C62-92-4.pdf
Title: Guide for the Application of Neutral Grounding in Electrical Utility Systems, Part IV – Distribution
Scope: This guide is concerned with the neutral grounding of single- and three-phase alternating current (ac) electric utility primary distribution systems with nominal voltages in the range of 2.4 kV to 34.5 kV. For the purpose of this guide, the term "distribution" includes the substation providing power to distribution feeders, the distribution feeders, and the distribution transformers providing service at utilization voltages. The scope of this guide does not include the grounding of the low-voltage secondary systems supplied by distribution transformers, at consumer-owned facilities that are covered by other standards such as the National Electrical Code (NEC).

PAR Number: PC62.92.5 (PE/SPD/HV)
Working Group: 3.5.7 Neutral Grounding
URL:
http://standards.ieee.org/board/nes/projects/C62-92-5.pdf
Title: Guide for the Application of Neutral Grounding in Electrical Utility Systems, Part V - Transmission Systems and Subtransmission Systems
Scope: The scope of this document is to give the basic factors and general considerations in selecting the class and means of neutral grounding for a particular ac transmission or subtransmission system, and the suggested method and apparatus to be used to achieve the desired grounding. Definitions of grounding terms used in this part of the guide may be found in IEEE Std. C62.92.1-2000 [1].
