概要 （英文）

THIS REPORT DESCRIBES THE CHARACTERISTICS OFLARGE ION UNDER THE SHIOBARA HVDC TEST LINE BY CARRYING OUT THE EXPERIMENTS OF THE VOLTAGE CHARACTERISTICS AND LATERAL PROFILES. MAIN RESULTSARE OBTAINED AS FOLLOWS. 1.APPLIED VOLTAGE HAS A LITTLE INFLUENCE ON LARGE ION DENSITY. 2.THE LARGE ION DENSITY INCREASES GRADUALLY UNDER THEDOWNWIND,REACHES THE MAXIMUM VALUE AT 67M FROM THE LINE CENTER AND THEN DECREASES GRADUALLY. BUT IT IS LARGER 2 3 TIMES THAN ITS BACKGROUND LEVEL (BGL) EVEN AT A POINT 200M FAR FROM THE LINE. 3.MAXIMUM LARGE ION DENSITY BECOMES NEARLY EQUAL TO 4*BGL AND OCCUPIES ABOUT 40% OF AEROSOLDENSITY LESS THAN 1MU DIAMETER.
