A Frequency Deviation Transducer with Fast Response,

摘要

A frequency deviation transducer having fast response and low ripple has been developed for use in power system control and relaying applications. Utilizing solid-state analog-type circuitry,response times of 18milliseconds with 2volts dc per hertz deviation are attained. Descriptions of circuitry functions, alinement and calibration procedures,and evaluation tests are included. (Author)
