为了弄清非极性聚合物的高场介电特性，研制了非极性聚合物无电容桥耗散电流的高精度测量系统。在高温高场区域，由于电极的电荷注入，耗散电流越来越大。此外，耗散电流波形的形状偏离正弦波形，表现出非线性特性。因此，高精度测量耗散电流（包括耗散电流的谐波）和研究交流场作用下的空间电荷效应具有重要意义。本文将讨论在交流高场下观测高场耗散电流的技术。
In order to clarify the high field dielectric properties, high accuracy measurement system for dissipation current of nonpolar polymers without Capacitance Bridge was developed. In high temperature and high field region, it is known that the dissipation current is getting large due to charge injection from the electrode. Furthermore the shapes of dissipation current waveform deviate from sinusoidal waveform and it shows nonlinear property. Therefore, it is important to measure the dissipation current with high accuracy, which include harmonics of dissipation current and to investigate the space charge effect under ac field. In this paper, we will discuss the technique, which enables the observation of the high field dissipation current under ac high field.
