Ground Fault Products for Ungrounded Systems

Installed Ground Fault Location for Ungrounded Systems

BENDER utilizes the latest technology to provide a complete solution for locating faults in ungrounded systems. When combined with our special ground detector, EDS series devices can locate a fault down to the load level. All ground fault location is done while the system remains online, providing a high level of system reliability and availability. The entire ground fault detection and location process can be automated to simplify notification of personnel in the event of a fault.

Installed EDS series modules provide an automated process of detecting faults. Each device can monitor up to twelve separate branches in parallel for any detected ground faults. Simple indication is provided to personnel when a fault is located.

  • EDS460 Series

    Ground fault location module for ungrounded AC/DC systems

    The EDS460 ground fault location module, in combination with the IRDH575 ground fault detector, locates branch faults in ungrounded AC/DC systems. Up to 12 separate branches may be monitored by one EDS460 device. Up to 90 EDS devices may be connected together, for a total of 1080 branches simultaneously monitored. The EDS460 works on both AC and DC systems, including systems with variable frequency drives (VFDs). Devices are interconnected via RS-485 to automate the process of locating faults. An LCD display shows which branch has the ground fault after it has been located. One common DPDT contact is built into the EDS460.

    The EDS460 is used with the IRDH575 ground detector and is designed for large power distribution networks. It features a common DPDT contact output.
