Voltage sensors mainly include electromagnetic voltage transformer, Hall voltage sensor, voltage divider sensor and new voltage sensor.
1. Electromagnetic Voltage Transformer
The principle of electromagnetic voltage transformer is similar to that of transformer. It consists of iron core, primary side coil and secondary side coil. The primary side coil is tested and tested.
2. Hall Voltage Sensor
Hall voltage sensor Hall voltage sensor mainly includes primary coil, magnetic ring, secondary coil, amplifier circuit and current limiting resistance in series with primary coil.
3. Voltage divider sensor
Voltage divider sensor Voltage divider sensor has resistance divider and capacitance divider, which directly converts the primary voltage into low voltage signal available for measuring instruments.
