Insulation fault locators for localisation of insulation faults in unearthed DC, AC and three-phase power supply systems (IT systems) Product description The insulation fault locators ISOSCAN® EDS44x are used in connection with the ISOMETER® iso685-D-P or the locating current injector PGH to locate insulation faults in unearthed power supply systems (IT systems). They detect locating current signals generated by the insulation monitoring device iso685-D-P or the locating current injector PGH and evaluate them correspondingly. Up to 12 measuring current transformers can be connected to an...
