A reclosing fault protection device detects a partial bypass state. Upon detecting the partial bypass state, the fault protection device implements a ground trip delay operating state. The ground trip delay operating state provides a delayed ground trip response characteristic.

A fault protection device tests a distribution for persistence of a fault using a selectable first fault testing procedure and a second fault testing procedure.

Fault testing fault protection device and method

Fault protection is provided with fuse saving in a power distribution system. An operating characteristic of a fault protection device protecting a portion of the power distribution system is configured in view of fuse melting characteristics. In this manner, fault protection is provided with fuse saving, when possible, with reduced service disruptions.
