Title: DEVELOPMENT OF FREQUENCY DIFFERENCE RELAY
Authors: Lal, B. M.
Keywords: ELECTRICAL ENGINEERING;FREQUENCY DIFFERENCE RELAY;POWER FREQUENCY SIGNAL;PAVER FREQUENCY
Issue Date: 1973
Abstract: The present investigation deals with the measurement of paver frequency, The power frequency signal is converted into &yncbrcnieed square wave which is than modulated at bi frequency. The nuabsr of pulses in each hell block is counted and converted in to proportional d. c* voltage which gives the corresponding value of the frequency. This d.c. voltage is differentiated to got the rate of change. Different level detectors are used for giving the tripping signal for different conditions of frequency and rate of change of frequency.
