P1860: Guide for Voltage Regulation and Reactive Power Compensation at 1000 kV AC and Above

Scope: This guide identifies principles for voltage regulation and reactive power compensation. This guide also provides acceptable voltage deviation range, as well as technical measures for voltage and reactive power adjustment and allocation in power systems at 1000 kV AC and above.

Purpose: This guide identifies voltage regulation and reactive power compensation recommendations for users involved in the planning, design, construction, and operation of power systems at 1000 kV AC and above. This guide may also be used for the purpose of scientific research.

P1861: Guide for On-site Acceptance Tests of Electrical Equipment and System Commissioning of 1000 kV AC and Above

Scope: This guide applies to on-site acceptance tests of electrical equipment and system commissioning of 1000 kV and above. It identifies a criterion and recommendations for test items, conditions, methods, and results.
The stated recommendations, both technical and testing, are universally needed for on-site acceptance tests and commissioning of 1000 kV AC and above, including power transformers, reactors, capacitive voltage transformers, current transformers, gas-insulated substations, grounding and disconnect switches, bushings, arresters, suspension and post insulators, insulating oil, SF6, secondary circuits, overhead transmission lines, and grounding devices.

Purpose: The intent of this guide is to identify on-site acceptance tests of 1000 kV AC and above electrical equipment. This guide also promotes the application and development of on-site acceptance test methodology.
It provides uniform technology specification recommendations for commissioning of 1000 kV AC and above transmission systems. It also provides the recommendations of testing, acceptance criterion, and safety specifications.
This guide also provides sufficient technical support for widespread and long distance Ultra High Voltage (UHV) AC transmission, and promotes system operating safety and reliability.

P1862: Recommended Practice for Overvoltage and Insulation Coordination of Transmission Systems at 1000kV AC and Above

Scope: This recommended practice applies to transmission system at 1000kV AC and above. It defines standard insulation levels and specifies procedures for selecting insulation levels of AC transmission lines and substations. It also specifies reliability criterion under switching and lightning overvoltages. Suggestions on insulation coordination design are described. Overvoltage mitigation measures are recommended according to the characteristics of such AC systems. Some examples of insulation coordination are also presented.

Purpose: Ultra-high Voltage (UHV) AC power transmission system is an effective approach to achieve efficient allocation of energy resources utilizing the advantages of large capacity with long distance, and low loss. Some countries have already carried out research on UHV technologies, and several UHV AC projects have been constructed and put into operation. This recommended practice is formulated specifically for the design and application of insulation coordination for transmission systems at 1000kV AC and above.
