> Directional Fault Sensing > Smart Tap
Line fault between two taps. Smart Tap generates fault direction flags at each sensing point. These flags can be sent to the
SCADA system and displayed on the operators single line diagram. These direction indicators represented as arrows on this
diagram point to the faulted line segment.
Faulted Line Section Isolated
MOMENTARY OR PERMANENT FAULT
PERMANENT FAULT
In the case of a permanent fault, The SCADA operator can open the switches which will isolate the faulted section after
the breakers have locked out for the remote controlled switches. If the switches are manually operated the crews can be
dispatched to the proper section to isolate the fault without the guess work of trying several locations before the proper location
is identified. The power to the customer can be quickly restored while the crews are clearing the source of the fault.
