An electromagnetic (EM) wave sensor technique is widely accepted for the detection of PDs. We installed a PD source in a 6.6 kV mold transformer tank.EM waves owing to the PDs were measured from the outside of the tank by an EM sensor. As the result, Detected electromagnetic wave spectra have a frequency range of about 20-40 MHz.}, pages = {153--156}, title = {変成器内部で生じる部分放電放射電磁波の周波数特性}, volume = {47}, year = {2018}, yomi = {カワコネ, ミツキ and シラハマ, ユウゴ and ナカムラ, トモヤ and サコダ, タツヤ and カワコネ, ミツキ and シラハマ, ユウゴ} }
