A Modulated-Frequency System of Telemeterings
Harold E. Renfro, Arthur Perry Peterson · Transactions of the American Institute of Electrical Engineers · 1945
WITH today's centralized control and supervision of power systems, it is essential that the man at the controls knows what is going on at all outlying stations and interconnection points. Telemetering equipment keeps him informed of load changes, transfer of power from one system to another, variations in voltage, and all other values that are necessary for efficient operation.
