Some Features and Performances of Type C Transmission-Line Fault Locators

Certain features of construction and operational performance of transmission fault locators now in use in Japan have been described. During the past decade, the locators have been proved competent for practical use. Although they are not yet completely accurate, the authors put the emphasis on achieving reliability, for the locators are normally in stand-by status and should operate with certainty on the rare occasions when faults occur. Each member of the technical committee on transmission line fault locator in Japan is making a continuous effort to obtain more accurate and more economical locators, and is also studying the fundamental problems, such as noise and propagation of locating pulse for various conditions.
