iMOA2020避雷器绝缘在线监测系统

iMOA2020避雷器绝缘在线监测系统

该系统（IED）利用基波法测量氧化锌避雷器的泄漏电流和阻性电流来实现动态监测避雷器的绝缘状况。iMOA2020避雷器监测智能处理器进行泄漏电流、阻性电流计算，并通过横向纵向比较、诊断、预警，从而实现避雷器绝缘状态的在线监测，经过处理后的结果数据和设备状态通过光纤以太网上传至MDD3000G智能处理器(iMAS2020G)。

主要功能 技术指标
◆实时监测氧化锌避雷器(MOA)的泄漏电流和阻性电流；
◆监测环境温度、湿度变化情况，以及根据温度湿度变化修正监测结果；
◆配合完备的专家系统进行数据分析；
◆提供越限报警功能。
