Measurement of current and voltages at infrasonic frequencies
- 15 Downloads
Electrical measuring instruments operating as vibrators can be used for measurements at infrasonic frequencies. The maximum frequency of the measured value is determined from the amplitude-frequency characteristic of the instrument on the basis of a given amplitude error.
It is advisable to use a moving-coil instrument with as large a damping as possible for operation as a vibrator.
A unidirectional scale has virtually no effect on the accuracy of measurements at frequencies specified in paragraph 1.
