Document Type and Number:
WIPO Patent Application WO/2019/124357
Kind Code:
A1
Abstract:
The present invention addresses the problem of evaluating an electric charge accumulated in an insulating material with a high degree of accuracy. An evaluation system (10) is provided with a holding portion (20) including a first electrode (21) and a second electrode (22) sandwiching a sample (100) of an insulating material, a chamber (30) accommodating the holding portion (20), and a current integrator (40). The current integrator (40) is interposed between a power source device (50) which applies a direct current voltage between the first electrode (21) and the second electrode (22) of the holding portion (20), and the first electrode (21). A wire (61) between the current integrator (40) and the first electrode (21) includes a conductor (611) at least part of which is not coated.
