In some aspects, a ground detection system may measure a difference from a tie point of the ungrounded electrical system and a ground point to determine if a grounded condition exists. The ground detection system may measure a plurality of signals at a plurality of distributed overload protection devices. The ground detection system may compare the plurality of signals from each of the plurality of distributed overload protection devices to stored threshold values. The ground detection system may determine a location of the grounded condition based at least in part on the comparing the plurality of signals from each of the plurality of distributed overload protection devices to the stored threshold values. In various embodiments, the location can be based on a length and an impedance of electrical circuit wiring. The ground detection system may display the location of the grounded condition on a display. Numerous other aspects are described.

Method and system for distributed ground detection

A modular intelligent electronic overload device that requires only a single configuration file to describe the device with all of the available options. Furthermore, the modular intelligent electronic overload device contains embedded application files that provide commonly used control algorithms into the non-volatile memory of the modular intelligent electronic overload device that can be accessed by a user to configure the device without the need for a personal computer. Finally, the modular intelligent electronic overload device configuration parameters can be stored to virtual non-volatile memory contained in an associated user interface device, allowing for easy replacement of the modular intelligent electronic overload device.
