Answer / deepak.vin208

If suddenly current in one phase of the line falls then there me and fault that particular phase got opened this will be detected by broken conductor protection by measuring the ratio of negative and positive sequence currents. in simple it is open circuit fault

<a href=" https://www.electricaltpoint.com/wave-trap-line-trap-working-construction-features-use-in-hv-trasmission-electricaltpoint/ "> Wave traps </a> or <a href=" https://www.electricaltpoint.com/wave-trap-line-trap-working-construction-features-use-in-hv-trasmission-electricaltpoint/ "> line traps </a> are used between the transmission line and power station to avoid carrier power dislocation in the power plant and cross talk with other power line carrier circuits connected to the same power station. They offer high impedance to carrier frequencies but pass 50 cycles power currents easily. They can be resonated at a single carrier frequency with a parallel capacitor. The tuning capacitors are protected against the surge voltages by a spark gap arranged in parallel
It is connected series with <a href=" https://www.electricaltpoint.com/radiant-heating-infrared-heating-and-induction-heating-eee/
"> transmission line </a>. it used for communication purpose. It will block the high frequency signal (communication signal) and allow the low frequency (power).
