ISOSCAN® EDS460-DG
绝缘故障评估仪EDS460-DG 与绝缘监视仪ISOMETER® IRDH575或定位电流发射器PGH组合使用，用于直流电源系统中(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绝缘故障评估仪进行相应的评估。一台EDS460-DG可以连接12个测量电流互感器。 如果有超过12路电路需要监视，通过RS-485接口可以连接90台EDS评估仪（BMS协议），因此可以同时监视1080个回路。最大扫描时间约为4…10 s，参考TGH1429。这个设备版本尤其适用于涉及高系统泄漏电容的系统 (20000 µFV，参考“技术参数”章节中的特征)。
