The quasioptimal linear filtering and increasing the noise resistance in case of measurement of parameters of electrical signals

The problem of quasioptimal linear filtering electrical signals of industrial frequency in input circuits of devices of relay protection and automatic equipment taking into account requirements of the GOST 32144-2013 to levels and frequencies of harmonic components of electrical voltage. There is a transfer function of the filter, and also implementation of such filters is discussed. Are calculated potential increase in a signal-to-noise ratio in comparison with traditionally used filters. It is given results of simulation of operation of the developed quasioptimal filters.
