Tips: Measuring requirements when using voltage sensors
To measure the voltage with a voltage sensor, it is generally required that the collected voltage signal is proportional to the measured voltage in amplitude, and the phase angles of the two are exactly the same or the difference is extremely small. In addition, there are the following basic requirements for the voltage sensor.
- The connection of the voltage sensor to the circuit under test should basically not affect the amplitude and waveform of the voltage under test.
- The voltage waveform obtained by the voltage sensor should be the same as the measured voltage waveform, and the voltage divider ratio should be independent of the measured voltage frequency and amplitude.
- The voltage divider ratio has nothing or basically nothing to do with atmospheric conditions (air pressure, temperature and humidity).
- The power consumed by the voltage sensor should not be large. Under certain cooling conditions, the temperature rise formed by the electrical energy dissipated by the voltage divider should not cause a change in the voltage divider ratio.
- The voltage sensor should not be interfered by the external electromagnetic field, and on the other hand, it should not produce strong electromagnetic interference from the external environment.
3 phase AC voltage transducer is a special voltage sensor for three-phase AC voltage measurement. Voltage transducer has a measuring range from AC 10V to 500V, supply voltage DC 12V/24V, output signal DC 0-5V/0-20mA/4-20mA. 3 phase voltage transducer is mainly used for power monitoring, power control and dispatching systems in petroleum, coal, metallurgy, railway and other industries.
