EDS Ground Fault Locator System (Standard)
In combination with the IRDH575 insulation monitor, the EDS series monitors and locates insulation faults on ungrounded AC and DC systems without disconnection of the electrical system. Fault location details are provided at a central point.
The EDS Fault Location System consists of the following components:
The main control unit: The IRDH575 is the central hub for the fault location system. This unit monitors the insulation resistance of the connected system to check for potential ground faults. Ground fault information is centralized to this unit via an RS485 bus. With this unit, users will know whether a ground fault does or does not exist.
The ground fault localizer: The EDS460/490 series is wired into your system and to the IRDH575. The EDS has up to 12 channels available to monitor 12 different parts of the system. The unit transmits a very small measuring pulse which travels through whatever ground fault may exist. Each subchannel is connected to an external current transformer to check for this pulse signal. With this unit, users will be able to localize a ground fault down to 12 different sub-systems.
The portable ground fault locator: The EDS309X series is a portable tool used to localize this transmitted pulse down to the smallest portion of the system creating the ground fault. A clamp is connected to a portable analyzer to check for the pulse signal travelling through any potential ground fault. With this unit, users will be able to localize a ground fault down to the specific cause. All ground fault location can be down while the system is still online.

IRDH575 |
 Ground Fault Monitor for Ungrounded Single-, Three-Phase AC and DC systems (part of location system)
|
|
The IRDH575 series monitors the insulation resistance of ungrounded 3(N)AC, AC/DC, and DC systems. Pertinent information is displayed via a digital LCD display. When used in combination with a unit from the EDS series with a current transformer, the IRDH575 may be used as an insulation fault locator.

EDS460-D |
Digital ground fault location evaluator for ungrounded AC/DC systems
|
|
The EDS460/490 series of fault evaluators, in combination with either the IRDH575 insulation monitor or a unit of the PGH insulation fault test series, localizes faults in ungrounded AC and/or DC systems. Potential ground faults are scanned via current transformers, then evaulated. Up to 12 current transformers can be connected to one EDS unit. Up to 90 EDS evaluators (1080 circuits) may be connected via an RS-485 interface (BMS protocol).
The EDS460-D's test current response range is 2 to 10 mA. An LCD digital display shows pertinent information and contains an easy to use menu. Two common alarm contacts connected to all 12 channels are built into the unit.
