Wave trap is used to trap waves of__________________?
Correct answer: B. higher frequencies entering generator or transformer units
- A. power frequencies
- B. higher frequencies entering generator or transformer units
- C. either of the above
- D. none of the above
Explanation
A wave trap, or line trap, presents high impedance to high-frequency carrier and surge signals while allowing normal power-frequency current to pass. It prevents these higher-frequency waves from entering generator or transformer equipment.
