- Page 2 ISOSCAN® EDS440 and EDS441 Insulation fault locator to locate insulation faults in ungrounded DC, AC and three-phase power supplies Intended use The insulation fault locators ISOSCAN® EDS440 and EDS441 are used to locate insulation faults in unearthed DC, AC and three-phase power supply systems (IT systems). Depending on the locating current injector, AC and three-phase systems can be monitored within the range from AC 42 to 1000 V;...
- Page 3 ISOSCAN® EDS440 and EDS441 Operating principle of the EDS system When an insulation monitoring device detects an insulation fault, The locating current is generated by the locating current injector. it starts the insulation fault location. It is limited in amplitude and time. The amplitude depends on the size of the existing insulation fault and the system voltage.
