Abstract
A PAPER entitled "A Modern Earth-Fault Relay Equipment for use on Systems Protected by Petersen Coils" was read in London recently by L. B. S. Golds and C. L. Lipman before the Institution of Electrical Engineers, and in it the authors dealt with the automatic isolation or indication of earth-faults on such systems. After discussing the operating principle of this type of protection, describing the working of a wattmeter-type relay, and enumerating the electrical constants of the type of system to which the protection is applied, the paper describes the application of the relay to an actual 66-kV. system.
