Use of oscillograph records for analyzing system performance
Abstract
Protection of present-day power systems is accomplished by a complex system of extremely sensitive relays that function only during a fault. Because relays are extremely fast, automatic oscillographs installed at convenient locations can be used successfully to determine the performance of protective equipment during abnormal conditions.
