| Abstract: | The electrostatic AC-DC voltage comparator for precise voltage measurement in voltage range of 100–1000 V and frequency range of 20–100,000 Hz was designed. The equality of AC and DC voltages transforms into horizontal positioning of the beam, which is registered by two photoelectric transducers. DC voltage was measured by voltage divider, standard cell and low-voltage comparator. The construction, main characteristics, and sources of errors are described. The comparison error has been determined as having the value of 0.003% at the voltage of 100 V and the value of 0.0009% at the voltage of 1000 V. |
