By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith.

Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonab

39、erved.IntroductionThis introduction is not part of IEEE Std 1898-2016, IEEE Standard for High-Voltage Direct-Current (HVDC) Compos-ite Post Insulators.This standard was prepared by the Working Group P1898 to establish standard specifications for high-voltage direct-current (HVDC) composite post insu
40、lators. Although composite post insulators for HVDC applications have been built and operated for over several years, only a limited number of papers, guides and standards are available and can be directly used for the manufacturing and testing of such insulators. The IEC polymeric insulator standar
41、d IEC 62217:2012 also covers insulators used in dc applications; however, a tracking and erosion test procedure for dc applications is not specified. Given the increased activity in HVDC transmission, a significant need has arisen for a standard that specifically covers the requirements and testing
42、of composite post insulators for HVDC applications.Significant accomplishments of this standard include the following:a) Establishment of a tracking and erosion test for HVDC composite post insulatorsb) Integration of test methodology for composite insulators with ceramic core, resin-impregnated fib
43、ers solid core, and hollow insulatorThe purpose of this document is to define the requirements and test code for HVDC composite post insulators. This standard utilizes feedback from manufacturers and end users. Radio interference and corona tests are not specified in this standard because the radio
44、interference and corona performances are not characteristics of the insulator alone.8Copyright 2017 IEEE. All rights reserved.Contents1. Scope .102. Normative references 103. De nitions . 114.
