System and method of measuring the electrical power transported by a line, compensation device for the spacing difference and the modulator by such a system for producing signals and other objects of the phase relationship of signals

摘要

The invention relates to a system intended to measure the electric power transported by a line of the supply of energy. / p & & p & of the elements 16, 18, for example of the transformers, detect of the current signals voltage. One of these analog signals is converted by a modulator 30 in a first signal module, which can rotate between two levels of the first clock intervals. A device 80 for the multiplication sets off the other analog signal under the control of the first signal module so that the two analog signals are multiply them and that the signal is proportional to the power transported by the line. A converter 90 converts this signal produced by a signal which is a module in proportion to the value of the signal produced and the power transported by the line 10. p / p field of application: counting of the electrical energy.
