ISOSCAN® EDS491-D
- 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
EDS460/490系列绝缘故障评估仪与绝缘监视仪ISOMETER® IRDH575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。由绝缘监视仪IRDH575或定位电流发射器PGH发出定位电流信号，并且由测量电流互感器扫面后由缘故障评估仪进行相应的评估。一台EDS可以连接12个测量电流互感器。 通过RS-485接口可以连接90台EDS评估仪（BMS协议）。因此，最多可以同时监视1080个回路。最大扫描时间约为4…10 s，参考TGH1394。
