Inspection and processing of several HF channel typical faults for 220 kV line

The HF channel is the important constituent of HF protection, its reliability leads to the correct response from the HP protection. How to deal with the HP channel fault is also the most difficult and concerned issue to the engineers on site. From the introdution of several HF channel typical malfunction and its inspection and test, this paper compares with good and bad points of common inspection processing methods, thus deepens understanding to the HF channel fault processing and knows some points which should be paid attention. It is a reference to HF channel fault's inspection and treatment.
