摘要

PPROBLEM TO BE SOLVED: To detect the occurrence of both tracking phenomenon and glow phenomenon. PSOLUTION: A two-phenomena detecting device 9 is constituted of a current detecting means for detecting AC current of a prescribed frequency supplied to an electric circuit, a peak value extraction means for extracting the peak value of every one cycle from the AC current detected by the current detection means, and an operation means for performing a predetermined arithmetical operation corresponding to the occurrence of the tracking breakdown and tracking degradation based on the extracted peak values. The device comprises also a peak value selection means for selecting the peak values equal to a preset threshold value or above from among a plurality of extracted peak values, a subtraction means for subtracting the selected peak value and a peak value extracted just before, and a counting means for counting the number of subtraction result applicable to each of the multiple preset threshold values, and is constituted such that, if each counting result is a preset threshold value or above, the occurrence of the tracking phenomenon or the glow phenomenon is determined.

要解决的问题：同时检测跟踪现象和辉光现象的发生。解决方案：二现象检测装置9由用于检测提供给电路的规定频率的交流电流的电流检测装置，用于从交流中提取每个周期的峰值的峰值提取装置构成。由电流检测装置检测的电流，以及用于基于提取的峰值执行与跟踪击穿和跟踪劣化的发生相对应的预定算术运算的运算装置。该设备还包括：峰值选择装置，用于从多个提取的峰值中选择等于或大于预设阈值的峰值;减法装置，用于减去所选择的峰值和紧接在其之前提取的峰值;以及计数装置，用于对可应用于多个预设阈值中的每一个的减法结果的数量进行计数，并且构成为使得如果每个计数结果为预设阈值或以上，则确定发生跟踪现象或发光现象。
