Advantages of Electrostatic Instrument
- Both the AC and DC voltage can be measured by using the electrostatic instrument.
- The electrostatic type instrument consumes very less power.
- The high value of voltage can be measured by using the instrument.
- In the rotary type electrostatic instrument, in spite of linear displacement, the angular displacement occurs between the fixed and the moving plates.
- The instrument has less Waveform and frequency error.
- No error occurs because of the stray magnetic field.
- The instrument is designed for large voltage.
Disadvantages of Electrostatic type instrument
- The non-uniform scale is used in the instrument.
- The force of very small magnitude involves in the instrument.
- The instrument is quite costly as compared to the other instrument.
- The size of the instrument is also very large.
