EDS440W-L-4 

Insulation faul locator EDS440W-L-4 acc. to IEC 61557-9 (DIN EN 61557-9, VDE 0413-9:2009-11) for insulation fault location systems with 12 measuring channels in unearthed AC, DC and AC/DC systems (IT systems) in combination with measuring current transformers.

The locating current signals generated by a locating current injector are detected by one or more integrated measuring current transformers and evaluated by the EDS440W-L-4 insulation fault locator. If the test current exceeds the response value, an alarm will be signalled over the display and the alarm relay. The operating and alarm values are made available via the BS bus interface.
