Ionisation potential applied across the electrodes of electrostatic tar precipitator is around_____________________?
Correct answer: D. 60 KV DC
- A. 230 V AC
- B. 60 KV AC
- C. 230 V DC
- D. 60 KV DC
Explanation
Electrostatic precipitators use a high-voltage direct-current field to create corona ionisation and charge tar or dust particles. The operating potential is commonly of the order of 60 kV DC, not ordinary AC or low-voltage supply.
