What are the Main Advantages and Disadvantages of Electrostatic Instruments?

The Main Advantages of the Electrostatic Instruments are mentioned Below:

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.

The Main Disadvantages of the Electrostatic Instruments are mentioned Below:

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.
