Prestige Group Maintenance Engineer Interview Questions, Process, and Tips

Q1. Why does some noise come from the high tension line.
Ans. 
Noise from high tension lines is caused by electromagnetic interference and corona discharge.
• High tension lines carry high voltage electricity, which can cause electromagnetic interference.

• Electromagnetic interference can generate noise in nearby electronic devices and equipment.

• Corona discharge occurs when the electric field surrounding the high tension line ionizes the air, creating a buzzing or crackling sound.

• Coron...read more
