voltage converter code 7, arithmetic unit 8 and indicator 9.

Webermeter works as follows.

The signal from the measuring winding enters the input of the time selector 2. If at this time the synchronizing signal came through block 4 to the input of the control pulse generator 3 and opened the selector 2, then the signal from the output of the latter is integrated by the integrator b, the voltage is converted into digital form code 7 and enters the third input of the arithmetic unit 8, the first input of which received a synchronizing signal. In this case, unit 8 operates in the mode of accumulating information with a converter. The synchronization signal delayed by the delay unit 5 goes through block 4 to the input of the pulse generator 3, as well as to the second input of the arithmetic unit 8, which operates in the mode of reading the information obtained from the output of the converter when the selector is reopened. This completes the measurement cycle, and the information from the arithmetic unit 8 is fed to the indicator.

The time relationships between the duration of the control signal, the magnetization reversal time, and the delay are chosen such that when the selector is opened again, the measured signal is absent and the external interfering EMF would not have time to change significantly. Elimination 718815

four

Neither internal factors affecting the error are provided by the fact that the opening time of the selector is the same when passing a measured signal and when forming a correction signal.
