Claims

25 through line 2 is connected to the inputs of block 3 and limiter 4, the output of block 3 is connected through block 5 to the first and second inputs of indicator 6, the third input of which is connected to the output of limiter .4. The device for telemetry mode parameters of power facilities works as follows. At the output of the modulator 1, pulses are generated, the duration of which is determined by the signal fed to bus 7, whose value is proportional to the voltage in the network under study. The amplitude of the signals at the output of the modulator 1 is determined by the signal fed to bus 8, whose value is proportional to the current in the network under study. Pulses from the output of modulator 1 through line 2 pass to the input of blocks 3 and 4. Block 3, by suppressing outward harmonics, selects the signal of instantaneous active power of the network under study. In block 5, the measured result is accumulated and the total and active power is calculated. At the output of limiter 4, a signal with a constant amplitude is formed, the duration of which is proportional to the voltage in the network under study. Indicator 6 displays the measured information: active and reactive power and voltage in the network under study. Thus, the proposed device allows for a continuous transmission line 8 to provide a continuous tele 8 measurement of the values of two types of power and voltage of the controlled network, i.e. It has more functionality.
