Impulse Characteristics of Aerial Spacer Cable

Although the overall performance record of aerial spacer cable on the Public Service Electric and Gas Company system has been excellent, the number of failures caused by lightning appears to be disproportionately high. To determine the optimum design criteria of this type of distribution system, a program of laboratory impulse tests was established. This paper presents the results of the laboratory tests, with volt-time curves for various components of the spacer cable system. This study is one of several performed by the Public Service Electric and Gas Company.
