The analysis and generalization of basic methods of estimation of parameters of electric signals are conducted. Dependence of phase change and amplitude of electric signal on a time domain which makes the stake of his period with the purpose of prevention of origin of power interruption and further its development is definite. A scientific novelty to work consists in development of correlation functions for the decision of tasks of fast-acting estimation of the promoted exactness of phase change and amplitude of sinusoidalno changing signals of industrial frequency on a short time domain which makes no more than a 10% duration of his period.
Keywords: electric signal, grid, phase change, amplitude, power object
