要約(英語): The direct current integrated charge method (Q(t) method) is a useful method to understand dielectric properties of insulating materials with a simple treatment. As total currents flowing through the insulating material are integrated by a capacitor, Q(t) data include various information about the material in them. To understand the Q(t) data, especially from the view point of electric charge behaviors, a parameter “charge ratio Q(tm)/Q(0)” which is the ratio of the initial charge amount Q(0)=CV and the Q(t) after time tm is introduced. An algorithm for classifying the electrode charge amount Q(0), the space charge accumulation amount Qspac(t), and the leakage current charge amount Qleak(t) using charge ratio is proposed and evaluated.
