ISOSCAN® EDS441
- 自动绝缘故障定位
- 应用于控制回路
- 12个测量通道用于测量电流互感器
- 连接CT监视
- 适用于各类通用系统
绝缘故障定位仪ISOSCAN® EDS44x与绝缘监视仪ISOMETER® iso685-D-P-CN或定位电流发射器PGH组合使用，用于不接地系统(IT系统)的绝缘故障定位。它们检测由绝缘监视仪iso685-D-P-CN或IRDH575或定位电流发射器PGH发出定位电流信号并且进行相应的评估。一台EDS44x可以连接12个测量电流互感器。同时可以有21个绝缘故障定位仪通过RS-485接口（BS总线协议）连接，因此可以监视252路输出电路。
