A New Standard for Impulse Testing Procedures for Insulated Conductors

In recognition of the approval of a new IEEE Standard (Guide) on Procedures for Impulse Voltage Testing of Insulated Conductors, a brief review of past developments and general progress in this field is presented. The early work of United States standards committees is noted, along with the later need for supplementation. A discussion of pertinent factors involved in standardization of impulse testing provides background for development of this standard. Comparison is made with a tentative draft of an Impulse Test Guide to be proposed by the International Electrotechnical Commission (IEC). Finally, areas for future research in this field are suggested.
