signals, namely the measurement of the partial dis-charge pulse current. The Roche coil works in mag-netic coupling, and the detecting circuit and the high-voltage circuit has no direct contact, so it is very suitable for the partial discharge site inspection in the high-voltage switchgear. 3 APPLICATION OF HIGH-FREQUENCY PULSE CURRENT SENSOR IN THE WAIST STATION FOR 35 KV SWITCH CABINET A 220 KV waist station is located on a hill, which is far from about 2 km to the north of Yang street , 4 DATA DETECTION AND ANALYSIS OF Lufeng town, Lufeng country of Chuxiong city , alti-SWITCHGEAR HIGH FREQUENCY FOR tude 1923 km, which covers an area of 22876 m PARTIAL DISCHARGE and put into production on December 25, 2009. It is one of the most important substation of Chuxiong During the 2-month testing for the Chuxiong waist Lufeng area. The main power source is supplied by station , we selected the data from April 23 to May 220 KV and 500 KV peace waist I changed back 25 in 2014 for effective analysis, and found that the line, 220 kV and waist II loop power. current data of the eight high-frequency pulse cur-rent sensor is normal, so we selected three sensor
