Direct-current (dc) ice-melting conditions, melting current, melting duration, and the amplitude of harmonics injected into the power grid are specified in this guide to support the safety, efficiency, and effectiveness of dc ice melting. The technical parameters, inspection, operation, and maintenance of dc ice-melting devices are also specified. The purpose of this guide is to provide dc ice-melting methods, which can be used to help prevent collapse of power transmission towers as well as disconnection and outage of transmission lines under continuous snow and freezing rain.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
