Higher frequencies entering generator or transformer units
All of the above
None of the above
Higher frequencies entering generator or transformer units
Wave trap also known as line
trap, or high frequency stopper, is a maintenance free parallel resonant
circuit, mounted in line on high-voltage (HV) AC transmission power line to
prevent the transmission of high frequency (40 kHz to 1000 kHz).
Hence, the correct option is
(B).
