Abstract
This paper describes a new electrical instrument for automatically recording variations of electrical functions at high speed. The rate of chart motion is lower than that of the oscillograph so that the envelope of an a-c. wave is produced. This recorder has been successfully applied in the analysis of breakdowns on transmission lines, giving data used as the basis of securing improved selective relay protection and for other problems involving automatic high-speed recording.
