Technical and economical investigation of Line-Traps in HV Substations

The line trap is basically a non-pass filter that is installed to prevent the unwanted passage of information-carrying waves in the power network. While the input impedance of the line trap is negligible for low frequency waves of power, this device exhibits a considerable impedance against high frequency waves. In this article, a complete overview of this line trap and its applications in the electrical industry has been made, and then the challenges and solutions of its installation and maintenance have been examined.
